[0037] In the claims, specification and drawings of the present utility model, if the terms "include", "have" and their variations are used, they are intended to mean "including but not limited to".

[0038] Please also read Figure 1 and Figure 2 Now, the side-opening back door structure assembly provided by the utility model is described. The side-opening back door structure assembly comprises a back door body 1, a door body guide portion 6 and a vehicle body support portion 7. The door body guide portion 6 is fixed to the side of the opening side 101 of the back door body 1. The vehicle body support portion 7 is arranged on the vehicle body and is arranged opposite to the door body guide portion 6. The door body guide portion 6 has a downward guide slope 2, which gradually tilts upward from the back to the front. The vehicle body support portion 7 has an upward support slope 3, which gradually tilts upward from the back to the front. The guide slope 2 and the support slope 3 can slide in a close fit along the front-to-back direction.

[0039] In this embodiment, the opening side 101 surface and the hinged side 102 surface are arranged opposite to each other, and the two are distributed along the left and right directions of the vehicle body. The hinged side 102 surface is rotatably connected to the vehicle body through components such as hinges.

[0040] In this embodiment, the door guide portion 6 and the tailgate, as well as the vehicle support portion 7 and the vehicle body are connected respectively by threaded fasteners. In order to avoid interference of the threaded fasteners when opening and closing the door, recessed grooves are provided on the door guide portion 6 and the vehicle support portion 7 to accommodate the nuts of the threaded fasteners.

[0041] Compared with the prior art, the side-opening tailgate structure assembly provided in the present embodiment has a problem that if the opening side 101 of the tailgate main body 1 sags, during the door closing process, the door body guiding portion 6 moves forward and approaches the vehicle body supporting portion 7, and the supporting slope 3 can form a supporting and guiding effect on the guiding slope 2. Since the supporting slope 3 and the guiding slope 2 are both slopes that gradually tilt upward from the back to the front, the door body guiding portion 6 can be lifted by the vehicle body supporting portion 7 during the door closing process, thereby achieving a guiding effect for closing the tailgate main body 1, and finally lifting the opening side 101 of the tailgate main body 1 to a standard height position, so that even if the tailgate main body sags, the accurate door closing effect can be achieved.

[0042] See also Figures 4 to 9 and Fig.11 In some specific embodiments, one of the guide slope 2 and the support slope 3 is formed by a groove 4, which is open in the front-to-back direction, and the other of the guide slope 2 and the support slope 3 is formed by a protrusion 5, which is plugged into the groove 4 front-to-back.

[0043] In this embodiment, the distribution modes of the protrusions 5 and the grooves 4 include the following two types:

[0044] 1) If the protrusion 5 is fixed to the vehicle body and the groove 4 is located in the back door body 1, the groove 4 opens forward, the upper wall surface of the groove 4 is the guide slope 2, and the upper side surface of the protrusion 5 is the support slope 3. Figures 4 to 8 As shown. Figure 8 In the process diagram shown, the vehicle body supporting portion 7 is fixed relative to the vehicle body. As the tailgate main body 1 is closed, the door body guiding portion 6 and the opening side 101 of the tailgate main body 1 move forward synchronously, and the groove 4 gradually approaches the protrusion 5. If the opening side 101 of the tailgate main body 1 sags to a certain extent, the guiding slope 2 on the upper side wall of the groove 4 gradually fits and contacts with the supporting slope 3 on the upper side of the protrusion 5, and gradually lifts the door body guiding portion 6 under the guiding action of the supporting slope 3. The increase in the height of the door body guiding portion 6 drives the opening side 101 to increase in height, and the sagging of the opening side 101 is gradually corrected. When the tailgate main body 1 is completely closed, the door body guiding portion 6 and the vehicle body supporting portion 7 reach the position shown in FIG. Figure 4 and Figure 5 It should also be noted that, when the back door body 1 does not sag on the opening side 101 , the inclinations of the guide slope 2 and the support slope 3 relative to the horizontal plane are the same.

[0045] 2) If the groove 4 is located on the vehicle body and the protrusion 5 is fixed to the back door body 1, the groove 4 opens to the rear, the lower wall of the groove 4 is the supporting slope 3, and the lower side of the protrusion 5 is the guiding slope 2. Fig.11 As shown. Fig.11 In the process diagram shown, the vehicle body supporting portion 7 is fixed relative to the vehicle body. As the tailgate body 1 closes, the door body guiding portion 6 and the opening side 101 of the tailgate body 1 move forward synchronously, and the protrusion 5 gradually approaches and inserts into the groove 4. If the opening side 101 of the tailgate body 1 sags to a certain extent, the guiding slope 2 on the lower side of the protrusion 5 gradually fits and contacts with the supporting slope 3 on the lower side wall of the groove 4, and gradually lifts the door body guiding portion 6 under the guiding action of the supporting slope 3. The increase in the height of the door body guiding portion 6 in turn drives the opening side 101 to increase in height, and the sagging of the opening side 101 is gradually corrected.

[0046] Since the cooperation between the guide bevel 2 and the support bevel 3 relies on the front-to-back plug-in cooperation between the groove 4 and the protrusion 5, the limiting dimension of the protrusion is expanded by the groove 4, which is beneficial to improving the reliability of the alignment between the guide bevel 2 and the support bevel 3.

[0047] See also Figures 4 to 9 and Fig.11In some specific embodiments, a plurality of grooves 4 may be provided in the up-down direction. Correspondingly, a plurality of protrusions 5 may be provided in the up-down direction and correspond one-to-one with the grooves 4, thereby forming a combination of a plurality of supporting slopes 3 and guide slopes 2 in the up-down direction. Through the multi-area contact guiding method, the inclination of the back door body 1 in the front-to-back direction can also be corrected. Combined with the correction function of the sagging of the back door body 1, the reliability and smoothness of the back door closing are further optimized.

[0048] In some embodiments, the bump 5 may be formed as follows: Figures 4 to 9 In the structure shown, the protrusion 5 includes a movable block 520 of a fixed block 510 distributed in the up-down direction, the fixed block 510 is fixed to the back door body 1 or the vehicle body, and the side of the fixed block 510 away from the movable block 520 forms a guide slope 2 or a support slope 3; the movable block 520 is elastically connected to the fixed block 510, and the movable block 520 is configured to be away from the preload of the fixed part. In the closed state, the side of the movable block 520 away from the fixed block 510 is tightly fitted with the side wall of the groove 4. In this embodiment, the elastic adaptation between the movable block 520 and the fixed block 510 enables the protrusion 5 to maintain the state of close contact between the support slope 3 and the guide slope 2 through the contact between the movable block 520 and the corresponding side wall of the groove 4 after being inserted into the groove 4, which is conducive to ensuring the reliability of the effect of lifting the opening side 101; at the same time, the protrusion 5 is fixed in the groove 4 in the up-down direction, effectively supporting and positioning the door body guide part 6, and avoiding the problem of the protrusion 5 shaking up and down in the groove 4 and generating abnormal noise during driving.

[0049] It should be noted that the fixed block 510 is a fixed member relative to the back door body 1 or the vehicle body. In actual use, if the protrusion 5 is fixed to the vehicle body and the groove 4 is located at the back door body 1, the fixed block 510 is arranged above the movable block 520, and the side (i.e., the upper surface) of the fixed block 510 away from the movable block 520 forms a supporting inclined surface 3, such as Figure 8 If the groove 4 is located in the body, the protrusion 5 is fixed to the back door body 1, the fixed block 510 is provided below the movable block 520, the fixed block 510 away from the side of the movable block 520 (ie, the lower surface) to form a guide slope 2, such as Fig.11 shown.

[0050] In some specific embodiments of activity block 520, see Figures 4 to 11, one end of the movable block 520 inserted into the groove 4 is defined as the movable insertion end 521, and the movable insertion end 521 is fixed to the fixed block 510. The movable block 520 is made of a material with a certain elasticity (such as rubber), so that the other end of the movable block 520 can be elastically swung in the up and down directions, and the movable block 520 as a whole is configured with a pre-tightening force to keep the other end away from the fixed block 510. In this embodiment, the movable block 520, the fixed block 510 and the door body guide part 6, or the movable block 520, the fixed block 510 and the vehicle body support part 7 can be made of the same material and integrally formed by injection molding or the like.

[0051] In other specific embodiments of the movable block 520, not shown in the figure, the movable block 520 and the corresponding fixed block 510 are separated from each other, and an elastic member (such as a spring, a rubber strip, etc.) is provided between the movable block 520 and the corresponding fixed block 510, and the elastic force of the elastic member is used to achieve the tightening and automatic resetting of the movable block 520 and the groove 4.

[0052] In some embodiments, an elastic adjustment support is provided between the fixed block 510 and the movable block 520 for adjusting the rigidity to avoid the problem that the rigidity of the movable block 520 is too small, resulting in poor support effect in the up and down directions, or the rigidity is too large, resulting in difficulty in inserting the entire protrusion 5. In this embodiment, the elastic adjustment support itself has a certain elastic deformation ability, and its rigidity and elasticity can be selected according to actual use requirements. In addition, the elastic adjustment support is suitable for the scene where the insertion end of the movable block 520 is fixed and the movable block 520 itself is elastically swung, and is also suitable for the scene where an elastic member is provided between the movable block 520 and the fixed block 510.

[0053] Specifically, in order to facilitate the installation of the elastic adjustment support, the movable block 520 and the fixed block 510 are respectively provided with a limiting groove 5404, and the elastic adjustment support is inserted into the limiting groove 5404. Fig. 9 More specifically, the cross-sectional area of ​​the elastic adjustment support gradually increases from its insertion end to the other end, and the cross-sectional profile is polygonal, so that the limiting member 530 is a polygonal conical table-shaped member as a whole.

[0054] See also Figures 6 to 8 and Fig.11In some embodiments, in order to facilitate the insertion of the movable block 520 into the groove 4, the side of the movable block 520 away from the fixed block 510 is defined as the movable surface 522, and the movable surface 522 is inclined in a first preset direction away from the fixed block 510, and the first preset direction is the direction from the insertion end of the movable block 520 itself to the other end; the side wall surface in the groove 4 that is closely fitted with the movable surface 522 is defined as a fitting surface, and the fitting surface is an inclined surface inclined in the same direction as the movable surface 522. In this embodiment, the protrusion 5 is formed as a triangular or trapezoidal component as a whole, which enhances the structural strength of the protrusion 5 itself, is conducive to improving the reliability of the protrusion 5 and extending its service life.

[0055] See also Figure 3 In some embodiments, a first shock absorber 8 is provided on the upper front edge of the back door body 1, and the first shock absorber 8 can abut against the rear side of the vehicle body. The first shock absorber 8 is a member with a certain elasticity, and can be made of rubber or other materials. Since the back door body 1 is close to the edge and is often spaced from the edge of the rear opening of the vehicle body, it cannot be effectively supported, and this area is more likely to cause shaking during the formation process. In addition, the area where the window frame 103 is located is a weakened area of ​​the back door body 1, and shaking is more easily transmitted. Therefore, the first shock absorber 8 is provided in the area close to the edge so that this area can be relatively fixed with the vehicle body, playing a supporting and shock absorbing role.

[0056] On the basis of the above embodiment, in order to make the back door body 1 bear more balanced force, a plurality of first shock absorbing members 8 are provided, and the plurality of first shock absorbing members 8 are respectively located on the left and right sides of the window frame 103 in the back door body 1. This arrangement also places the shock absorbing member in the area most prone to shaking, provides shock absorbing support for key areas, and can also reduce the number of first shock absorbing members 8 provided while ensuring the shock absorbing effect.

[0057] In some embodiments, the front side of the tailgate body 1 is also provided with a sealing strip 9 extending circumferentially along the tailgate body 1. The sealing strip 9 can abut and seal against the edge of the opening on the rear side of the vehicle body. Based on this, the first shock absorber 8 is arranged on the outer ring of the annular structure formed by the sealing strip 9, that is, the first shock absorber 8 is closer to the edge of the tailgate body 1.

[0058] In some embodiments, the back door body 1 may be Figures 1 to 3 In the structure shown, the back door body 1 includes a back door inner panel 110 and a back door outer panel 120 arranged in sequence from front to back, a spare tire installation area 121 is formed on the back door outer panel 120, and a plurality of second shock absorbing members 10 arranged around the spare tire installation area 121 are arranged on the back door outer panel 120, and the rear end of the second shock absorbing member 10 abuts against the front side of the spare tire. The second shock absorbing member 10 is a member with a certain elasticity, and can be made of rubber or other materials.

[0059] Due to the heavy weight of the spare tire, it is prone to晃动 due to inertia during driving, resulting in problems such as抖动 and abnormal noise of the outer panel 120 of the rear door. In this embodiment, the second shock-absorbing member 10 is used to support and limit between the outer panel 120 of the rear door and the spare tire, reducing the晃动 amplitude of the spare tire, effectively improving the problem of the spare tire driving the outer panel 120 of the rear door to shake, and enhancing the NVH performance.

[0060] Furthermore, in order to achieve effective support and reduce the number of second support members, the second shock-absorbing members 10 are respectively arranged on both sides of the upper part of the spare tire installation area 121 and on one side of the lower part of the spare tire installation area 121 close to the opening side 101, as Figure 1 and Figure 2 shown, strengthening the support for the area close to the opening side 101 and enhancing the effectiveness of the support points.

[0061] On the basis of the above embodiment, referring to Figure 2 and Fig.10 , the rear door main body 1 further includes a reinforcing plate 130 arranged between the inner panel 110 of the rear door and the outer panel 120 of the rear door. The front side of the reinforcing plate 130 is adhesively connected to the outer panel 120 of the rear door, and the four peripheral edges of the reinforcing plate 130 are respectively adhesively connected to the inner panel 110 of the rear door to form a reinforcing cavity between the reinforcing plate 130 and the inner panel 110 of the rear door. The reinforcing plate 130 of this embodiment is an arched plate structure, forming a reinforcing cavity by connecting with the inner panel 110 of the rear door respectively around, building a reliable force transmission channel between the outer panel 120 of the rear door and the inner panel 110 of the rear door, which is beneficial to quickly disperse the acting force transmitted by the spare tire to the outer panel 120 of the rear door to the inner panel 110 of the rear door, and further transmit it to the vehicle body, extending the force transmission path and enhancing the dissipation effect of the acting force; at the same time, the reinforcing plate 130 also effectively strengthens the overall structural strength and stiffness of the rear door main body 1, directly weakening the shaking energy transmitted by the spare tire, and playing a promoting role in reducing problems such as shaking and abnormal noise of the rear door main body 1.

[0062] On the basis of the above embodiment, the upper edge of the reinforcing plate 130 is bent forward to form an upper leg 131, the lower edge of the reinforcing plate 130 is bent forward to form a lower leg 132, the left edge of the reinforcing plate 130 is bent forward to form a left leg 133, and the right edge of the reinforcing plate 130 is bent forward to form a right leg 134. The upper leg 131, the lower leg 132, the left leg 133 and the right leg 134 are respectively supported and connected to the inner panel 110 of the rear door; in the cross-section parallel to the left-right direction, the cross-sections of the left leg 133, the main body of the reinforcing plate 130 and the right leg 134 form a "Ji"-shaped cross-section structure; in the cross-section parallel to the up-down direction, the cross-sections of the upper leg 131, the main body of the reinforcing plate 130 and the lower leg 132 form a "Ji"-shaped cross-section structure.

[0063] Furthermore, referring to Figure 2 and Fig.10The middle part of the spare tire installation area 121 is left empty, and the upper edge of the empty part is bent forward to form an empty leg 136, and the empty leg 136 is closely connected to the back door inner panel 110.

[0064] To facilitate installation of the second shock absorber 10 , in some embodiments, a reinforcing plate 130 is provided corresponding to the spare tire installation area 121 , a front end of the second shock absorber 10 is fixed to the reinforcing plate 130 , and a rear end of the second shock absorber 10 extends rearwardly out of the tailgate outer panel 120 .

[0065] On the basis of the above embodiment, a reinforcing boss 135 protruding backward is formed on the reinforcing plate 130, and the second shock absorbing member 10 is mounted on the reinforcing boss 135 in a one-to-one correspondence. The specific mounting method can be: a screw is arranged on the front side of the second shock absorbing member 10, a threaded seat is arranged on the rear side of the reinforcing boss 135, and the mounting is achieved by screwing the screw and the threaded seat; of course, the mounting method of the second shock absorbing member 10 can also be other methods, such as clamping, etc., which are not listed here one by one.
