[0038] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0039] In the description of the utility model, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0040] The up, down, front, back, left and right directions involved in the present invention refer to the directions of the car in the O-XYZ coordinate system of the vehicle, the origin O coincides with the center of mass of the vehicle, the front end refers to the X direction parallel to the ground and pointing forward, the rear end refers to the X direction parallel to the ground and pointing backward, the left side refers to the Y direction parallel to the ground and pointing to the left side of the driver, the right side refers to the Y direction parallel to the ground and pointing to the right side of the driver, the upper end refers to the Z direction pointing upwards through the point O, and the lower end refers to the Z direction pointing downwards through the point O.

[0041] During the driving process of the vehicle, in order to keep the tailgate of the vehicle stable and avoid the tailgate shaking or colliding with the side of the vehicle body, the tailgate and the side of the vehicle body are respectively provided with limiting structures that can limit each other, so as to achieve the effect of limiting after the tailgate is closed; for the limiting block on the side of the vehicle body, the conventional practice is to set a base plate for the installation of the bracket structure on the rear side of the vehicle body, and after the bracket structure is installed on the base plate set on the outer panel of the water flow channel, the limiting block is installed on the bracket structure. Therefore, the stiffness of the base plate directly determines the stiffness of the installation point of the limiting block, but the stiffness of the base plate is insufficient, and the bracket structure has a certain height, resulting in that after the tailgate is closed, during the driving process of the vehicle, the bracket structure is easy to shake and the position is unstable, and the limitation of the tailgate on the side of the vehicle body is unstable, which cannot meet the limitation requirements of the tailgate.

[0042] In the embodiment of the utility model, a limit block installation structure (hereinafter referred to as the installation structure) is provided for the limit block on the vehicle body side, which is used to improve the rigidity of the limit block installation point, so that the limit block can limit the tailgate more stably and meet the limit requirements of the tailgate. Figure 1 and Figure 2 The mounting structure 100 includes a water trough outer plate 110, a pillar reinforcement plate 120 and a first limit block 130. The water trough outer plate 110 is usually arranged on the rear side of the vehicle body. The water trough has a tendency to extend from top to bottom and is used to guide rainwater and other impurities on the vehicle body to the outside of the vehicle to prevent water from entering the interior of the vehicle to corrode the sheet metal or damage the internal environment of the vehicle; the pillar reinforcement plate 120 is located at the rear of the vehicle body and is used to connect the top side beams of the vehicle body, the rear top cross beam, the wheel cover support frame and other structures. It has high strength, can support the roof and protect the safety of the passengers in the vehicle, and enhance the strength of the vehicle body and the safety performance of the vehicle.

[0043] like Figure 5The water trough outer plate 110 has a first mounting portion 111, and the pillar reinforcement plate 120 has a second mounting portion 121. The first mounting portion 111 and the second mounting portion 121 are stacked and fixedly connected. The first limiting block 130 is used to limit the tailgate and is installed on the side of the first mounting portion 111 away from the second mounting portion 121. The first mounting portion 111 on the water trough outer plate 110 serves as the mounting point of the first limiting block 130. Since the first mounting portion 111 and the second mounting portion 121 are fixedly connected, and the pillar reinforcement plate 120 has high strength, the combination of the water trough outer plate 110 and the pillar reinforcement plate 120 can enable the first mounting portion 111 to provide a mounting point with high rigidity for the first limiting block 130. When the tailgate is closed and the vehicle is driving, the force applied to the first limiting block 130 when it collides or contacts with the limiting block on the tailgate side can be directly transmitted to the second limiting block 130 through the first mounting portion 111. The second mounting portion 121 has a high-strength column reinforcement plate 120 to resist the torsion and bending caused by the force, so that the first limit block 130 provides stable limiting for the tailgate; in addition, the first limit block 130 is directly mounted on the first mounting portion 111, and the bracket structure is removed, which can reduce the weight of the entire vehicle, reduce the tooling cost, shorten the distance between the first limit block 130 and the mounting point, and the first limit block 130 is not easy to deform or shake, and can provide a stable limiting effect for the tailgate, reduce the unstable factors of the tailgate during the vehicle's movement, and meet the limiting requirements of the tailgate.

[0044] It should be noted that the mounting structure 100 in the present invention can be applied to vehicles of different models. In different models, the pillar reinforcement plate 120 is located at the rear of the vehicle body and can be stacked and connected with the water tank outer plate 110. For example, for SUV, MPV, station wagon and other models, the pillar reinforcement plate 120 is set as the D-pillar reinforcement plate of the vehicle body; for hatchback, sedan and other models, the pillar reinforcement plate 120 is set as the CD-pillar reinforcement structure of the vehicle body.

[0045] The fixed connection method of the first mounting part 111 and the second mounting part 121 is not limited to thread fastening, bonding, riveting, welding, etc. Exemplarily, threaded fasteners, such as bolts and nuts, are provided, the bolts pass through the first mounting part 111 and the second mounting part 121 in sequence, the nuts are sleeved on the bolts and tightened, and the first mounting part 111 and the second mounting part 121 can be locked to achieve the fixed connection between the first mounting part 111 and the second mounting part 121; or, an adhesive is provided between the first mounting part 111 and the second mounting part 121, and the first mounting part 111 and the second mounting part 121 are mutually attached and bonded and fixed; or, the first mounting part 111 and the second mounting part 121 are mutually attached and welded and fixed. It can be understood that by fixing the first mounting part 111 and the second mounting part 121 by welding, the connection between the first mounting part 111 and the second mounting part 121 is more stable and will not loosen due to heavy loads, vibrations or temperature changes. There is a high degree of sealing between the two, which can prevent dust and water from penetrating into the interior of the vehicle. In addition, the surface of the first mounting part 111 can be kept flat to facilitate the installation of the first limit block 130 to the first mounting part 111.

[0046] like Figure 1 , except for the overlapping area between the first mounting portion 111 and the second mounting portion 121, the projections formed by other areas of the water trough outer plate 110 and the column reinforcement plate 120 in the arrangement direction of the two are at least partially overlapped, and some areas are attached to each other, so that the water trough outer plate 110 and the column reinforcement plate 120 are not only connected by the first mounting portion 111 and the second mounting portion 121, but also can be combined with each other through other parts. The water trough outer plate 110 and the column reinforcement plate 120 can be combined to form a structurally stable force system. The water trough outer plate 110 can disperse and transmit the force borne by the first limit block 130 to different parts of the column reinforcement plate 120 through different connection points, thereby reducing stress concentration. The water trough outer plate 110 and the column reinforcement plate 120 jointly resist the load, so that the rigidity of the limit block installation point is further enhanced.

[0047] Exemplarily, the edge areas of the water trough outer plate 110 and the column reinforcement plate 120 are attached to each other and fixed by welding, which can increase the contact area between the water trough outer plate 110 and the column reinforcement plate 120, increase the force transmission area, and facilitate the dispersion of stress. Alternatively, a connecting bracket is set on an area with a certain distance between the water trough outer plate 110 and the column reinforcement plate 120 and the projection overlaps in the arrangement direction, and the two ends of the connecting bracket are respectively connected to the water trough outer plate 110 and the column reinforcement plate 120. The connecting bracket provides support to the water trough outer plate 110 and the column reinforcement plate 120, which can reduce the deformation of the water trough outer plate 110 and the column reinforcement plate 120 in the arrangement direction of the two, and strengthen the structural strength of the water trough outer plate 110 and the column reinforcement plate 120 after the combination; of course, multiple connecting brackets can be set and distributed at different positions, so that the water trough outer plate 110 can be supported at different positions.

[0048] In one embodiment, referring to Figure 1 , Figure 2 and Figure 7 The water trough outer plate 110 has a mounting boss 112 protruding away from the pillar reinforcement plate 120, and the side wall opposite to the mounting boss 112 and the second mounting portion 121 forms a first mounting portion 111. When the tailgate is closed, the first mounting portion 111 is located closer to the tailgate. The protruding distance of the first mounting portion 111 can compensate for the distance that the first limit block 130 is relatively far away from the tailgate side limit block due to the removal of the bracket structure. The first limit block 130 does not need to be increased in length or additionally made. It can cooperate with the tailgate side limit block to limit at the original length, and can overcome the defects of the first limit block 130 being easy to shake and unstable in position due to the lengthening of the first limit block 130.

[0049] It can be understood that since the first mounting portion 111 is raised relative to other areas of the water trough outer plate 110, the mounting boss 112 can block water from other areas on the surface of the water trough outer plate 110 from flowing toward the first limit block 130, thereby reducing the risk of water ingress and improving the waterproof performance of the mounting structure 100; in addition, the mounting boss 112 can disperse the load and stress on the water trough outer plate 110, reduce the risk of local stress concentration, make the structure of the water trough outer plate 110 more stable, and further strengthen the rigidity of the mounting point of the first limit block 130.

[0050] In addition, in order to make the first mounting portion 111 and the second mounting portion 121 fit each other and be welded and fixed, the column reinforcement plate 120 can also be provided with a protruding structure protruding toward the water channel outer plate 110, and the second mounting portion 121 is provided at the part where the protruding structure fits the first mounting portion 111, so that the first mounting portion 111 can be matched and connected with the second mounting portion 121, and the strength of the column reinforcement plate 120 is simultaneously strengthened. When the tailgate is closed, the first limit block 130 is subjected to the collision and pressing force of the limit block on the side of the tailgate. Since the first mounting portion 111 and the second mounting portion 121 are both in a protruding state, the first mounting portion 111 can be supported by the second mounting portion 121 to strengthen the strength of the installation point of the first limit block 130.

[0051] Specifically, refer to Figure 7 The mounting boss 112 has a protruding portion 1121 and a supporting portion 1122. The supporting portion 1122 is arranged around the outer periphery of the supporting portion 1122. One end of the supporting portion 1122 is connected to other areas of the water channel outer plate 110, and the other end is connected to the protruding portion 1121. When the tailgate is closed, the supporting portion 1122 has a tendency to extend toward the tailgate to raise the protruding portion 1121. At least a portion of the protruding portion 1121 forms the first mounting portion 111. The surface of the protruding portion 1121 is flat, so that the installation of the first limit block 130 is more stable. When the tailgate is closed, the first limit block 130 is subjected to the force of the tailgate side limit block in the Y direction toward the outside of the vehicle and toward the pillar reinforcement plate 120. A reinforcing rib may be provided on the supporting portion 1122, and the extending direction of the reinforcing rib is set to be approximately parallel to the force direction of the first limit block 130, so as to reduce the risk of deformation of the water channel outer plate 110 when the first limit block 130 is subjected to force. Similarly, reinforcing ribs are provided on the protruding structure of the column reinforcing plate 120 to further improve the rigidity of the second mounting portion 121 and the mounting point of the first limiting block 130 .

[0052] In one embodiment, referring to Figure 2The water trough outer plate 110 includes a bottom plate 114 and a side plate 115 connected to the side of the bottom plate 114. The mounting boss 112 is arranged on the bottom plate 114. A flow channel 113 is defined between the mounting boss 112 and the side plate 115. The flow channel 113 passes through the extension direction of the water trough outer plate 110. The flow channel 113 can be used for water flow on the surface of the water trough outer plate 110 to pass through, so that the water flow can be smoothly discharged out of the vehicle, preventing the water flow from excessively accumulating on the water trough outer plate 110 and overflowing to the top of the mounting boss 112, thereby effectively reducing the risk of water entering the installation position of the first limit block 130. It should be noted that the side panel 115 refers to the side wall of the water trough outer panel 110 in the Y direction; further, the water trough outer panel 110 is provided with side panels 115 on both sides in the Y direction, and a flow channel 113 is defined between the mounting boss 112 and at least one side of the side panel 115, and the side walls on both sides of the water trough outer panel 110 guide the water flow downward to the ground, blocking the water flow in the Y direction or entering the interior of the vehicle.

[0053] As a specific embodiment of the flow channel 113, a flange that turns upward is provided on the side of the water trough outer plate 110 close to the vehicle trunk, and the flange blocks the water flow from entering the trunk. The side wall of the flange facing away from the trunk forms a side plate 115. The side plate 115 and the mounting boss 112 are spaced apart from each other and form a flow channel 113 for water flow to pass through, so as to guide the water flow to the outside of the vehicle. Furthermore, the side wall at the top of the support portion 1122 of the mounting boss 112 is arranged to gradually approach the side plate 115 from top to bottom, and the side wall plays the role of guiding the water flow to the channel between the mounting boss 112 and the flange, reducing the splashing of the water flow when it flows to the mounting boss 112, and further reducing the risk of water entering the installation position of the first limit block 130.

[0054] like Figure 6 In the present invention, the first mounting portion 111 is located at the lower part of the center of the water trough outer plate 110 in the vertical direction, that is, the first limit block 130 is installed at the lower position of the water trough outer plate 110. The upper part of the tailgate is usually connected to the vehicle body through other structures such as support rods. The first limit block 130 installed at the lower position of the water trough can limit the lower part of the tailgate, which can enhance the overall position stability of the tailgate when it is in a closed state.

[0055] The fixing installation method of the first limit block 130 to the first mounting portion 111 is not limited to threaded fastening, welding, riveting, etc. Exemplarily, the side wall of the first limit block 130 facing the first mounting portion 111 is set to a metal material, and the first limit block 130 is fixed to the surface of the first mounting portion 111 by welding, and the connection between the first limit block 130 and the first mounting portion 111 is relatively stable. Specifically, the second mounting portion 121, the first mounting portion 111 and the first limit block 130 are stacked in sequence, and the contacting surfaces are fixed by welding. The second mounting portion 121, the first mounting portion 111 and the first limit block 130 form an integral structure. The first limit block 130 and its mounting point have a high bonding strength, which can jointly resist the collision impact applied by the tailgate side limit block, and is not easy to deform or shake.

[0056] Reference Figure 5 The first limit block 130 includes a shell 131 and a frame 132. The frame 132 is arranged inside the shell 131. The frame 132 and the shell 131 are formed into an integral structure through an injection molding process. The frame 132 is arranged to be made of a metal material with a certain structural strength. The shell 131 is arranged to be made of an elastic material such as TPEE (thermoplastic polyester elastomer). The shell 131 can produce a certain deformation when it contacts the limit block on the tailgate side, providing a buffer during the collision between the limit block on the tailgate side and the limit block on the body side, avoiding the hard contact of the two limit blocks and causing damage to other components. The frame 132 provides support for the shell 131 to prevent the shell 131 from excessive deformation and affecting the limiting effect on the tailgate.

[0057] Regarding the method of welding and fixing the first limit block 130 and the first mounting part 111, a part of the skeleton 132 is exposed from the side of the outer shell 131 toward the first mounting part 111, and the surface of the skeleton 132 facing the first mounting part 111 contacts the first mounting part 111 and is welded to the first mounting part 111. The installation of the first limit block 130 to the installation point is more convenient, and the connection position between the first limit block 130 and the first mounting part 111 has a high sealing performance, which can prevent the water in the water flow channel outer plate 110 from penetrating into the interior of the column reinforcement structure.

[0058] In another embodiment, a first limit block 130 is provided and is threadedly fastened to the first mounting portion 111. Specifically, the mounting structure 100 includes a threaded locking member 140 and a threaded mounting member 150. The threaded mounting member 150 is connected to the side of the second mounting portion 121 away from the first mounting portion 111. The threaded locking member 140 is penetrated through the second mounting portion 121, the first mounting portion 111 and the first limit block 130, and is threadedly connected to the threaded mounting member 150 to lock the first limit block 130 on the first mounting portion 111, thereby achieving a fixed connection between the first limit block 130 and the first mounting portion 111. Specifically, the threaded locking member 140 is configured as a bolt, and the threaded mounting member 150 is configured as a nut. The screw of the threaded locking member 140 is passed through the threaded mounting member 150, the second mounting portion 121, the first mounting portion 111 and the first limit block 130, and is threadedly connected to the nut. Screwing the threaded locking member 140 can press the head of the threaded locking member 140 against the first limit block 130, thereby completing the installation and fixation of the first limit block 130 to the first mounting portion 111.

[0059] The threaded mounting member 150 is configured to be detachably connected to the second mounting portion 121. When the threaded locking member 140 is screwed, the threaded mounting member 150 can be moved closer to or farther from the second mounting portion 121. When the first limiting block 130 is locked, the threaded mounting member 150 presses against the column reinforcement plate 120, and clamps the first limiting block 130, the first mounting portion 111 and the second mounting portion 121 together with the head of the threaded locking member 140. Alternatively, the threaded mounting member 150 is configured to be welded to the side of the second mounting portion 121 facing away from the first mounting portion 111. The threaded mounting member 150 and the second mounting portion 121 have a high connection strength. Screwing the threaded locking member 140 can change the pressing force of the threaded locking member 140 on the first limiting block 130. The first limiting block 130 can be installed to the first mounting portion 111 by screwing the threaded locking member 140, and the installation of the first limiting block 130 is more convenient.

[0060] Reference Figure 4 The mounting structure 100 also includes a column inner plate 160, which is located on the side of the column reinforcement plate 120 facing away from the water tank outer plate 110. The column inner plate 160 is connected to the column reinforcement plate 120, and can form a column structure on the vehicle body, such as a D column, a CD column, etc., to strengthen the strength of the column reinforcement plate 120. There is a gap between the column inner plate 160 and the column reinforcement plate 120, and the gap can be used for the threaded mounting member 150 to be placed. The threaded mounting member 150 uses the space provided by the column structure for installation, and does not affect the position layout of other structures. For example, the threaded mounting member 150 is pre-welded to the second mounting portion 121, and then the column reinforcement plate 120 and the column inner plate 160 are combined to form a column structure.

[0061] like Figure 5The first limiting block 130 includes a limiting portion 133 and a side wing 134. The side wing 134 is connected to the side of the limiting portion 133. The limiting portion 133 protrudes away from the first mounting portion 111 relative to the side wing 134. The limiting portion 133 is used to cooperate with the limiting block on the tailgate side for limiting. The threaded locking member 140 is connected to the side wing 134 and locks the side wing 134 to the first mounting portion 111 to fix the first limiting block 130 to the water channel outer plate 110. The side wing 134 is arranged on the side of the limiting portion 133 to increase the contact area between the first limiting block 130 and the first mounting portion 111, and improve the connection strength between the first limiting block 130 and the first mounting portion 111. In addition, the side wing 134 is thinner than the limiting portion 133, and the threaded locking member 140 is more convenient for fixing the first limiting block 130.

[0062] It can be understood that the side wing 134 and the limiting portion 133 both have a skeleton 132 inside to strengthen the structural strength of the side wing 134 and the limiting portion 133, so that the connection between the side wing 134 and the first mounting portion 111 is more stable, and the limiting portion 133 is not easy to be excessively deformed; further, the skeleton 132 is arranged in the area where the limiting portion 133 is away from the tailgate. On the one hand, the limiting portion 133 has a certain strength and can cooperate with the tailgate side limiting block for limiting. On the other hand, the part of the limiting portion 133 close to the tailgate has a certain flexibility, which can provide a buffer when the tailgate side limiting block collides with the first limiting block 130.

[0063] In addition, a sealing gasket is arranged between the head of the threaded locking member 140 and the side wall, or a sealing gasket is arranged between the first limit block 130 and the first mounting portion 111 to strengthen the sealing of the connection position between the first limit block 130 and the first mounting portion 111 and reduce the risk of water ingress.

[0064] Reference Figure 5 The first limiting block 130 has a first collision surface 135, which is located at the end of the first limiting block 130 facing away from the first mounting portion 111. The first collision surface 135 is tilted and is used to cooperate with the limiting block on the tailgate side for limiting; the first collision surface 135 is gradually tilted toward the outer side in the Y direction in the backward direction of the X direction. The first collision surface 135 can guide the limiting block on the tailgate side when the tailgate is closed, and apply a force in the Y direction and toward the inner side of the vehicle to the tailgate, so that the tailgate maintains a stable position in the Y direction.

[0065] It can be understood that the rear part of the vehicle body should be provided with two symmetrically distributed mounting structures 100, which are spaced apart in the Y direction and located on both sides of the tailgate. The first limit block 130 in the mounting structure 100 on the left side of the Y direction has a first collision surface 135 inclined toward the left side along the rearward direction of the X direction, and the first limit block 130 in the mounting structure 100 on the right side of the Y direction has a first collision surface 135 inclined toward the right side along the rearward direction of the X direction.

[0066] In addition, refer to Figure 6 and Figure 7 A second limit block 200 is provided on the tailgate side. The second limit block 200 has a second collision surface 210. The second collision surface 210 is also inclined, and the inclination direction is consistent with the inclination direction of the first collision surface 135. The first collision surface 135 cooperates with the second collision surface 210 to limit the tailgate in the Y direction.

[0067] Furthermore, the first collision surface 135 and the second collision surface 210 are respectively provided with grooves and protrusions that cooperate with each other, so that the tailgate is limited in multiple directions. For example, one of the first collision surface 135 and the second collision surface 210 is provided with grooves arranged at intervals along the Z direction, and the other is provided with protrusions arranged at intervals along the Z direction, and the protrusions and the grooves extend along the Y direction. When the tailgate is closed, the protrusions are inserted into the grooves along the Y direction without blocking the closing process of the tailgate, and the Z direction limitation of the tailgate is achieved after the tailgate is closed.

[0068] Reference Figure 1 , Figure 3 and Figure 6 The utility model also provides a vehicle, including the above-mentioned mounting structure 100 and a tailgate 300, wherein the tailgate 300 includes a tailgate body 310 and a second limit block 200 (i.e., a side limit block of the tailgate 300) mounted on the tailgate body 310. When the tailgate 300 is closed, the first limit block 130 and the second limit block 200 collide with each other, and the first collision surface 135 contacts and abuts against the second collision surface 210 to limit the position of the tailgate 300. Since the rigidity of the mounting point of the first limit block 130 in the mounting structure 100 is improved, the tailgate 300 is continuously and stably limited by the first limit block 130, and the position remains stable during the driving of the vehicle.

[0069] It should be noted that the vehicle referred to in the present utility model may be a private car, such as a sedan, SUV, MPV or pickup truck. The vehicle may also be an operating vehicle, such as a van, bus or truck. The vehicle may be a gasoline vehicle or a new energy vehicle. When the vehicle is a new energy vehicle, it may be a hybrid vehicle or a pure electric vehicle.

[0070] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the utility model. In addition, the embodiments of the utility model and the features in the embodiments can be combined with each other without conflict.
