DETAILED DESCRIPTION

[0059] In order to make the technical personnel in the technical field to which the present application belongs to understand the present application more clearly, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0060] In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides various specific examples of processes and materials, but those of ordinary skill in the art may recognize the application of other processes and / or the use of other materials.

[0061] See also Figure 1 and Figure 2 , respectively showing the front view and rear view of the side-opening back door 100 in the related art, a door lock 130 and a limit structure 190 are arranged on one side of the side-opening back door 100, and an upper hinge 141 and a lower hinge 142 are arranged on the other side. In the related art, the side-opening back door 100 usually first meets the equipment requirements of the spare tire 160, and all the door locks 130 and hinges are arranged around the placement space of the spare tire 160. Figure 3 The cross-sectional view of the door lock 130 of the side-opening back door 100 in the related art is shown. The sealing strip 120 and the door lock 130 are arranged side by side in the thickness direction of the back door, and in the width direction of the back door, the sealing strip 120 and the door lock 130 completely overlap. Figure 2 and Figure 3 It can be seen that the door lock 130, the limiting structure 190 and the handle 180 completely occupy the left space, leaving no space for arranging the taillight. The right hinge will occupy the upper position, and in order to arrange the spare tire 160 in the best position, the right eccentric arrangement will be adopted, and the spare tire 160 will be placed on the right side close to the hinge side, leaving no space for arranging the taillight on the right side of the spare tire 160.

[0062] As an important exterior and functional part, the taillights are required to be arranged symmetrically on both sides and cannot be blocked by the spare tire 160. Based on the above analysis, due to space limitations, the taillights cannot be arranged on the side-opening back door 100, and all taillight functions can only be placed completely on the body, specifically on both sides of the opening of the luggage compartment at the rear end of the body. The need to set up a mounting structure for the taillights increases the complexity of the body-in-white structure.

[0063] In addition, the side-opening tailgate 100 mainly meets off-road requirements, and hanging the spare tire 160 is an important functional requirement. If the taillight is forcibly arranged on the side-opening tailgate 100, the strength of the tailgate will be greatly reduced, which will lead to insufficient performance of the tailgate during off-road driving (such as vibration, abnormal noise, and deformation of the tailgate).

[0064] To this end, the present application provides a side-opening back door 100 and a vehicle, aiming to solve the problems existing in the current side-opening back door to at least a certain extent. The side-opening back door 100 provided by the present application can not only be equipped with a conventional taillight, but also improve the strength and performance of the back door, reduce the vibration of the back door under extreme off-road conditions, and improve the off-road performance. The content of the present application will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0065] For the convenience of description, the various directions involved in the embodiments are defined as follows: In the field of vehicle technology, the length direction of the vehicle is usually called the X direction or longitudinal direction, the width direction of the vehicle is called the Y direction or transverse direction, and the height direction of the vehicle is called the Z direction or vertical direction. The side-opening tailgate is installed at the rear end of the vehicle, and the width direction of the side-opening tailgate is also the width direction of the vehicle, that is, the Y direction; the height direction of the side-opening tailgate is also the height direction of the vehicle, that is, the Z direction; the thickness direction of the side-opening tailgate is also the length direction of the vehicle, that is, the X direction. The interpretation of the relevant direction expressions in the following embodiments can refer to the above content.

[0066] See also Figure 4 , Figure 5 and Figure 8 In the first embodiment of the present application, there is provided a side-opening back door 100, including a door body 110 and a sealing strip 120, a door lock 130, a hinge assembly 140, a first tail light 151 and a second tail light 152 installed on the door body 110. The door body 110 is the main body of the side-opening back door 100, and is used to be arranged at the opening of the luggage compartment of the vehicle to cover the opening of the luggage compartment, and at the same time serves as the installation base of various accessories on the side-opening back door 100. The sealing strip 120, the door lock 130 and the hinge assembly 140 are conventional accessories on the side-opening back door 100, and the sealing strip 120 is arranged on the inner side of the door body 110, and is used to seal the door body 110 and the vehicle body. The door lock 130 is used to lock with the lock seat of the vehicle body. The door lock 130 is arranged on the first side of the inner side of the door body 110. The hinge assembly 140 is used to hinge the door body 110 with the vehicle body. The hinge assembly 140 is arranged on the second side of the inner side of the door body 110 and is located outside the area surrounded by the sealing strip 120. For ease of understanding, the first side is defined as the left side of the side-opening back door 100 and the second side is defined as the right side of the side-opening back door 100. The first side hereinafter is equivalent to the left side (abbreviated as L) and the second side is equivalent to the right side (abbreviated as R). Of course, in other embodiments, the right side of the side-opening back door 100 is also defined as the first side and the left side of the side-opening back door 100 is defined as the second side.

[0067] See also Figure 5 and Figure 6 , unlike the conventional side-opening back door 100 in which the sealing strip 120 is arranged on the door lock 130, in the present application, the door lock 130 is located in the area surrounded by the sealing strip 120, that is, the door lock 130 and the sealing strip 120 are staggered in the width direction of the door body 110. By improving the side-by-side arrangement of the door lock 130 and the sealing strip 120 along the X direction to side-by-side arrangement along the Y direction, the space occupied by the door lock 130 and the sealing strip 120 in the thickness direction of the door body 110 can be reduced, so that the door lock 130 and the sealing strip 120 are used to avoid the space for arranging the first tail light 151 in the thickness direction of the door body 110. The first tail light 151 is arranged on the first side of the outer side surface of the door body 110, and the first tail light 151 and the door lock 130 are arranged side by side in the thickness direction of the door body 110 without overlapping, and the first tail light 151 and the door lock 130 do not interfere with each other.

[0068] See also Figure 7 In some embodiments, in order to further optimize the arrangement of the first taillight 151, the sealing strip 120 and the door lock 130, along the thickness direction of the door body 110, the sealing strip 120 overlaps with the door lock 130, and the sealing strip 120 does not exceed the position of the door lock 130, that is, the sealing strip 120 is completely located in the extension space of the door lock 130 in the X direction, and the sealing strip 120 does not occupy the thickness space of the door body 110. Along the width direction of the door body 110, the sealing strip 120 and the door lock 130 are arranged side by side and both overlap at least partially with the first taillight 151, which is equivalent to that the sealing strip 120 and the door lock 130 are both located in front of the first taillight 151, and the first taillight 151 does not occupy additional space in the Y direction, and does not affect the arrangement of the spare tire 160.

[0069] By arranging the sealing strip 120 and the door lock 130 side by side in the Y direction and the door lock 130 being located in the area surrounded by the sealing strip 120, not only is there a space for installing the first taillight 151, but also the size of the opening of the luggage box (such as Fig.24 As shown, the opening size L of the luggage case is the size in the middle of the sealing strip 120. The opening size of the luggage case is as large as possible to facilitate the placement of luggage. For the side-opening back door 100 of the same size, the present application arranges the door lock 130 in the area surrounded by the sealing strip 120, which not only solves the arrangement problem of the first taillight 151, but also increases the opening size of the luggage case. The door lock 130 is arranged in the dry area (the area surrounded by the sealing strip 120), which improves the sealing wading performance of the side-opening back door 100.

[0070] See also Figure 5In some embodiments, the side-opening back door 100 is further provided with a limiting structure 190, and the vehicle body is provided with a limiting groove that cooperates with the limiting structure 190. The limiting structure 190 is located below the door lock 130, and the limiting structure 190 and the door lock 130 are located in the area surrounded by the sealing strip 120. After the door lock 130 is locked, the limiting block of the limiting structure 190 extends into the limiting groove and snaps into place, playing the role of preventing the back door from sinking in the Z direction and preventing the back door from rotating backward in the X direction.

[0071] See also Figure 8 , Fig. 9 and Fig.10 In the present application, the height of the hinge at the top of the hinge assembly 140 is higher than that of the conventional side-opening back door 100, and is higher than the height of the second taillight 152, so that the second taillight 152 and the hinge at the top of the hinge assembly 140 are staggered in the Z direction, solving the problem of space arrangement of the hinge side taillight. The height of the second taillight 152 is the same as that of the first taillight 151, meeting the appearance requirements.

[0072] It should be noted that the second taillight 152 and the hinge located at the top of the hinge assembly 140 are staggered in the Z direction, which means that the second taillight 152 and the hinge located at the top of the hinge assembly 140 are not completely overlapped in the Z direction, that is, the overall height of the hinge located at the top of the hinge assembly 140 is higher than the second taillight 152. The specific expression may be that the height of the upper side of the hinge located at the top of the hinge assembly 140 is higher than the height of the upper side of the second taillight 152, and the height of the lower side is higher than the height of the lower side of the second taillight 152, that is, the second taillight 152 and the hinge located at the top of the hinge assembly 140 are arranged side by side in the Z direction and partially overlap; the specific expression may also be that the height of the lower side of the hinge located at the top of the hinge assembly 140 is higher than the height of the upper side of the second taillight 152, that is, the second taillight 152 and the hinge located at the top of the hinge assembly 140 are arranged side by side in the Z direction and do not overlap.

[0073] In the design stage, the position of the taillight is first determined according to the styling effect, and then the position of the sealing strip 120, the door lock 130, and the hinge at the top of the hinge assembly 140 are determined according to the position of the taillight. In order to stably support the door body 110, the hinge assembly 140 usually includes at least two hinges. Figure 8 The specific structure and distribution of the hinge assembly 140 in some embodiments are shown. Figure 8 The hinge assembly 140 includes an upper hinge 141 and a lower hinge 142 spaced apart along the height direction of the door body 110, and the height of the second taillight 152 is smaller than the upper hinge 141 and larger than the lower hinge 142. In other embodiments, if the overall height of the side-opening back door 100 is larger, the hinge assembly 140 may include 3 or 4 hinges.

[0074] See also Fig.11 , Fig.12 and Fig.13 , shows a schematic diagram of the structure of the door body 110 and a schematic diagram of the structure of the sub-components in some embodiments, the door body 110 includes a back door outer panel assembly 111 and a back door inner panel assembly 112 connected; the first taillight 151 and the second taillight 152 are both installed on the back door outer panel assembly 111; the sealing strip 120, the door lock 130 and the hinge assembly 140 are all installed on the back door inner panel assembly 112. The back door outer panel assembly 111 and the back door inner panel assembly 112 are connected by at least one connection method selected from threaded fasteners 162, riveting, welding, bonding, and FDS, and the specific connection method is not limited in this application.

[0075] In some embodiments, see Fig.13 and Fig.14 The back door inner panel assembly 112 includes a back door inner panel 1121, a middle reinforcement unit 1123 connected to the back door inner panel 1121, a door lock reinforcement 1122, and a hinge reinforcement 1124. The door lock reinforcement 1122, the middle reinforcement unit 1123, and the hinge reinforcement 1124 are sequentially distributed along the width direction of the door body 110. The door lock reinforcement 1122 is connected to the left side of the back door inner panel 1121 and at least covers the area where the door lock 130 is located. The hinge reinforcement 1124 is connected to the right side of the back door inner panel 1121 and at least covers the area where the hinge is located. The middle reinforcement unit 1123 is connected to the middle area of ​​the back door inner panel 1121 and at least covers the connection area of ​​the fasteners for fixing the spare tire 160.

[0076] The middle reinforcement unit 1123, the door lock reinforcement 1122, and the hinge reinforcement 1124 are all enclosed with the tailgate inner plate 1121 to form a cavity 112a structure. The cavity 112a structure reduces the vibration transmitted from the spare tire 160 to the tailgate to a minimum, improves the strength and vibration mode of the tailgate, solves the problem of tailgate vibration and deformation under extreme off-road conditions and poor road surfaces (bad roads) after the spare tire 160 is installed, and improves off-road riding comfort.

[0077] See also Fig.14In some embodiments, the back door inner panel 1121 is provided with a window frame 11211 for mounting a rear windshield, the upper ends of the door lock reinforcement 1122 and the hinge reinforcement 1124 are extended to the upper edge of the window frame 11211, and the middle parts of the door lock reinforcement 1122 and the hinge reinforcement 1124 are connected to the middle reinforcement unit 1123 to completely cover the lower edge and both side edges of the window frame 11211. The door lock reinforcement 1122, the middle reinforcement unit 1123 and the hinge reinforcement 1124 are all enclosed with the back door inner panel 1121 to form a closed cavity 112a structure, so that the vibration of the spare tire 160 is dispersedly transmitted from the middle reinforcement unit 1123 to various areas of the side-opening back door 100, and the vibration is weakened during the transmission process by absorbing energy through the cavity 112a structure, thereby preventing excessive vibration shock from being transmitted to weak points.

[0078] In the related art, the side-opening tailgate 100 does not need to be equipped with a taillight, so the height of the uppermost hinge in the hinge assembly 140 is lower than the lower edge of the window frame 11211. For the embodiment in which the hinge assembly 140 includes an upper hinge 141 and a lower hinge 142, the height of the upper hinge 141 is lower than the lower edge of the window frame 11211. Since the window frame 11211 has less material around the periphery and is relatively weak in strength, the installation position of the upper hinge 141 is set below the lower edge of the window frame 11211 to avoid the weak area and improve the structural strength of the hinge installation point. However, in the present application, since it is necessary to install the second taillight 152 and the position of the second taillight 152 has been determined (based on the styling effect), the height of the uppermost hinge in the hinge assembly 140 is increased so that the height of the uppermost hinge in the hinge assembly 140 is flush with the lower edge of the window frame 11211. For this purpose, please refer to Fig.10 , Fig.13 and Fig.21 The hinge reinforcement 1124 and the tailgate inner panel 1121 form a cavity 112a structure at the hinge installation location and above, so that the upper cavity 112a structure formed by the tailgate inner panel 1121 and the hinge reinforcement 1124 at the lower edge of the window frame 11211 is enlarged, which is more conducive to improving the structural performance of the window frame 11211 of the side-opening tailgate 100, improving the structural strength of the weak points of the tailgate, and improving various performances of the tailgate.

[0079] In some embodiments, any one of the door lock reinforcement 1122, the middle reinforcement unit 1123 and the hinge reinforcement 1124 can be set as an integrated structure, for example, formed in one step by casting or stamping, and its material can be high-strength steel, cast aluminum, magnesium-aluminum alloy and other alloy materials. In other embodiments, any one of the door lock reinforcement 1122, the middle reinforcement unit 1123 and the hinge reinforcement 1124 can also be set as a plurality of parts connected as a whole by welding, threaded fasteners 162, riveting, FDS and the like, and the plurality of parts can be made of the same material or different materials, and their thicknesses can be the same or different. The structure, material and thickness of the door lock reinforcement 1122, the middle reinforcement unit 1123 and the hinge reinforcement 1124 of the present application are not limited, and can meet the strength requirements of the side-opening back door 100.

[0080] In some embodiments, the door lock reinforcement 1122, the middle reinforcement unit 1123 and the hinge reinforcement 1124 are all connected by parts of different materials and / or thicknesses. Specifically, the main force-bearing structures (parts used to connect the spare tire 160, the door lock 130, the hinge, the handle 180 or other accessories) in the door lock reinforcement 1122, the middle reinforcement unit 1123 and the hinge reinforcement 1124 are made of high-strength materials and have a large thickness, and other parts that only play the role of supporting the back door outer panel assembly 111, wiring harness, sensors (such as radar, reversing image camera, etc.) are made of ordinary materials and / or have reduced thickness. Different parts are welded and fixed, and the segmented welded closed structure obtained by using parts of different material thicknesses and materials ensures structural strength and reduces structural weight and cost.

The door lock reinforcement plate 11222 is the main force-bearing structure of the door lock reinforcement member 1122, and the door lock 130 is connected to the back door inner plate 1121 and the door lock reinforcement plate 11222 at the same time. The door lock reinforcement plate 11222 is made of high-strength materials such as high-strength steel, with a yield strength of more than 460MPa and a thickness of more than 1.5mm.

[0082] See also Fig.17 and Fig.18 The middle reinforcement unit 1123 includes an upper reinforcement beam 11231, a lower reinforcement beam 11232, a left reinforcement beam 11233, a right reinforcement beam 11234 and a window frame reinforcement plate 11235. The upper reinforcement beam 11231, the lower reinforcement beam 11232, the left reinforcement beam 11233 and the right reinforcement beam 11234 are connected to form a frame structure 11236. The frame structure 11236 can be in a quadrilateral or a "well" shape. Fig.18 In the middle reinforcement unit 1123 of the embodiment shown, the left reinforcement beam 11233 and the right reinforcement beam 11234 have the same structure and size, and mainly carry the spare tire 160. The left and right ends of the upper reinforcement beam 11231 extend outward from the connection between the upper reinforcement beam 11231 and the left reinforcement beam 11233 and the right reinforcement beam 11234, and are respectively connected to the door lock reinforcement plate 11222 and the hinge reinforcement plate 11242. The right end of the lower reinforcement beam 11232 extends rightward from the connection between the lower reinforcement beam 11232 and the right reinforcement beam 11234, and is connected to the hinge reinforcement plate 11242. The four components of the frame structure 11236 are all made of high-strength materials such as high-strength steel, with a yield strength of more than 460MPa and a thickness of more than 1.5mm. The window frame reinforcement plate 11235 is connected to the upper reinforcement beam 11231. The window frame reinforcement plate 11235 is used to strengthen the lower edge of the window frame 11211. Its length is smaller than the upper reinforcement beam 11231. The window frame reinforcement plate 11235, together with the first upper corner reinforcement plate 11221 and the lower corner reinforcement plate 11223, can be made of steel plate or aluminum plate with a thickness not exceeding 1 mm and a yield strength of 200 to 350 MPa.

[0083] Considering the high structural strength of the frame structure 11236, it can significantly strengthen the corresponding area of ​​the back door inner panel 1121 after being connected to the back door inner panel 1121. For this purpose, please refer to Fig.14 In some embodiments, a weight-reducing hole 1121a is provided in the middle of the back door inner panel 1121, and the frame structure 11236 is located at the periphery of the weight-reducing hole 1121a and is connected to the area of ​​the back door inner panel 1121 located at the periphery of the weight-reducing hole 1121a. The frame structure 11236 is provided with at least four spare tire mounting holes 1123a, which are used to install the spare tire 160 mounting bolts. The spare tire mounting holes 1123a are provided in at least one group of relative reinforcing beams of the frame structure 11236, and the spare tire mounting holes 1123a are located in close contact with the back door outer panel assembly 111. Correspondingly, please refer to Fig.12 , the back door outer panel assembly 111 also needs to be provided with an assembly hole 1111b for the bolt to pass through. In some embodiments, the spare tire mounting hole 1123a and the assembly hole 1111b are each provided with 6, and the 6 spare tire mounting holes 1123a are symmetrically distributed on the left reinforcing beam 11233 and the right reinforcing beam 11234.

[0084] Based on the arrangement position of the first taillight 151 of the side-opening back door 100 in some embodiments, it overlaps with the door lock 130 in the X direction, and the second taillight 152 overlaps with the upper hinge 141. In this case, the spare tire 160 must be arranged in the middle of the side-opening back door 100, symmetrically, to avoid blocking the taillight and affecting the lighting requirements. Therefore, when arranging the spare tire installation hole 1123a, it is also necessary to arrange the spare tire installation hole 1123a in the middle of the side-opening back door 100.

[0085] See also Fig.19 and Fig. 20The hinge reinforcement member 1124 includes a second upper corner reinforcement plate 11241, a hinge reinforcement plate 11242 and at least one nut plate 11243 connected to each other. The first upper corner reinforcement plate 11221 is used to reinforce the upper right corner area of ​​the window frame 11211, and its shape is adaptively adjusted according to the shape of the upper right corner of the window frame 11211. The second upper corner reinforcement plate 11241 can be made of a steel plate or an aluminum plate, with a thickness not exceeding 1 mm and a yield strength of 200 to 350 MPa. The hinge reinforcement plate 11242 at least covers all installation locations of the hinge assembly 140, and a plurality of hinge mounting holes 1124a are provided on the hinge reinforcement plate 11242, and each nut plate 11243 is respectively connected to the hinge mounting hole 1124a of the hinge reinforcement plate 11242. The hinge reinforcement plate 11242 is the main force-bearing structure of the hinge reinforcement 1124. The hinge is connected to the back door inner panel 1121, the hinge reinforcement plate 11242 and the nut plate 11243 at the same time. The hinge reinforcement plate 11242 is made of high-strength materials such as high-strength steel, with a yield strength of more than 460MPa and a thickness of more than 1.5mm. The nut plate 11243 is mainly used to provide a thread for effective screw connection with the hinge mounting bolt. Its load-bearing requirement is between the second upper corner reinforcement plate 11241 and the hinge reinforcement plate 11242, and its material strength and thickness are both between the second upper corner reinforcement plate 11241 and the hinge reinforcement plate 11242.

[0086] In a specific implementation, the door lock reinforcement plate 11222, the upper reinforcement beam 11231, the lower reinforcement beam 11232, the left reinforcement beam 11233, the right reinforcement beam 11234 and the hinge reinforcement plate 11242 are all made of high-strength steel with a yield strength of about 500 MPa and a thickness of 2 mm; the nut plate 11243 is made of a medium-strength steel plate with a yield strength of about 350 MPa and a thickness of 1.5 mm; the first upper corner reinforcement plate 11221, the lower corner reinforcement plate 11223, the window frame reinforcement plate 11235 and the second upper corner reinforcement plate 11241 are all made of high-strength steel with a yield strength of about 275 MPa and a thickness of 0.7 mm. The joints of each sub-component are welded and fixed.

[0087] See also Fig.21 In the embodiment where the hinge assembly 140 includes an upper hinge 141 and a lower hinge 142, the upper reinforcing beam 11231 and the lower reinforcing beam 11232 are both connected to the hinge mounting hole 1124a of the hinge reinforcing plate 11242. Specifically, the hinge reinforcing plate 11242 is provided with two sets of hinge mounting holes 1124a, and two nut plates 11243 are provided accordingly. The right end of the upper reinforcing beam 11231 is connected to the upper part of the hinge reinforcing plate 11242, and supports the lower right corner of the window frame 11211 and the installation place of the upper hinge 141; the right end of the lower reinforcing beam 11232 is connected to the lower part of the hinge reinforcing plate 11242, and supports the lower right corner of the back door and the installation place of the lower hinge 142.

[0088] The door lock reinforcement 1122, the middle reinforcement unit 1123 and the hinge reinforcement 1124 are all located on the side of the back door inner panel 1121 facing the back door outer panel assembly 111, and play a role in supporting the back door outer panel assembly 111. Fig.16 , Fig.18 and Fig. 20 In some embodiments, the door lock reinforcement 1122, the middle reinforcement unit 1123 and the hinge reinforcement 1124 are each provided with one or more outer panel support members 1125, and the outer panel support member 1125 is welded and fixed to the parts connected thereto on the door lock reinforcement 1122, the middle reinforcement unit 1123 and the hinge reinforcement 1124, and is bonded to the back door outer panel assembly 111 through a shock-absorbing adhesive. For the embodiment in which the back door inner panel 1121 is provided with a weight-reducing hole 1121a, an outer panel support member 1125 can be installed at the weight-reducing hole 1121a. The function of the outer panel support member 1125 is only to support the back door outer panel assembly 111 from deformation and to improve the mode of the back door outer panel assembly 111. Therefore, the strength and / or thickness of the outer panel support member 1125 is less than that of the nut plate 11243. The outer panel support member 1125 can be made of a steel plate or an aluminum plate, the thickness of which does not exceed 1 mm, and the yield strength is between 200 and 350 MPa.

[0089] Please combine Fig. 22 The transmission principle of the closed cavity 112a in the back door inner panel assembly 112 is as follows: when driving on a bad road, the spare tire 160 drives the back door to vibrate up and down and left and right. The vibration of the spare tire 160 is dispersed and transmitted by the middle reinforcement unit 1123, wherein the upper reinforcement beam 11231 connects the upper hinge installation structure on the right side of the hinge reinforcement plate 11242 with the window frame 11211, as shown in FIG. Fig.21 As shown, the installation performance of the upper hinge 141 can be better enhanced. The upper hinge 141 installation position adopts a closed annular cavity 112a structure, which absorbs vibration in the closed annular cavity 112a structure to prevent vibration deformation from being transmitted to the weak point (the upper edge and side edge of the window frame 11211). The door lock reinforcement 1122 and the hinge reinforcement 1124 respectively strengthen the left and right edges of the window frame 11211. The above structures jointly reduce the deformation risk at the weak point of the back door and improve the road durability. In addition, due to the reinforcement of the hinge installation structure, the anti-sinking performance of the side-opening back door 100 is improved.

[0090] In some embodiments, in addition to the weight-reducing holes 1121a surrounded by the middle reinforcement unit 1123, the back door inner panel 1121 may be provided with other weight-reducing holes 1121a according to actual needs, for example, another weight-reducing hole 1121a is provided in the left area of ​​the back door inner panel 1121. The reinforcement structure in the back door inner panel assembly 112 adopts a segmented welded closed structure, which can be made of different material thicknesses and materials, and cooperates with a plurality of weight-reducing holes 1121a on the back door inner panel 1121, thereby jointly reducing the structural weight and cost of the back door inner panel assembly 112.

[0091] See also Figure 7 and Fig.24 In some embodiments, the first side of the back door inner panel 1121 is provided with an extension edge 11212 that is bent toward the back door outer panel assembly 111 and extends outward. The back door inner panel 1121 is a stamped sheet metal part in a groove shape, which is used to accommodate the middle reinforcement unit 1123, the door lock reinforcement 1122, and the hinge reinforcement 1124. The extension edge 11212 is located at the groove and extends outward. The sealing strip 120 is installed on the extension edge 11212. The thickness of the sealing strip 120 does not exceed the groove depth, so that the sealing strip 120 does not occupy additional space in the thickness direction. The part where the door lock 130 is coupled with the lock seat of the vehicle body is set on the groove wall of the groove and is locked with the lock seat of the vehicle body along the X direction.

[0092] The back door outer panel assembly 111 includes a back door outer panel 1111 and two tail light mounting plates 1112 respectively mounted on both sides of the back door outer panel 1111. The tail light mounting plates 1112 are welded and fixed to the back door outer panel 1111. The tail light mounting plates 1112 are connected to the back door inner panel 1121, the door lock reinforcement plate 11222, and the hinge reinforcement plate 11242 by structural adhesive. By designing the back door outer panel assembly 111 as a split structure, the back door outer panel 1111 with a larger area can be a simple sheet metal structure with a simple preparation process. The tail light mounting plate 1112 with a relatively complex structure is small in size and is independently formed. The first tail light 151 and the second tail light 152 are respectively mounted on the corresponding tail light mounting plates 1112. Since the projection of the first taillight 151 and the door lock 130 in the X-direction overlap, and the projection of the second taillight 152 and the upper hinge 141 in the X-direction partially overlap or are located close to each other, the door lock reinforcement plate 11222 that reinforces the installation area of ​​the door lock 130 and the hinge reinforcement plate 11242 that reinforces the installation area of ​​the upper hinge 141 can also strengthen the installation structure of the first taillight 151 and the second taillight 152, thereby solving the problem of insufficient tailgate performance due to the presence of the taillights.

[0093] See also Fig.23 and Fig.24 In some embodiments, the side-opening back door 100 further includes a spare tire 160, which is mounted on a spare tire bracket 161, and the spare tire bracket 161 is connected to the door body 110 via a threaded fastener 162. Fig. 22In some embodiments, three spare tire support blocks 170 are provided on the middle reinforcement unit 1123. The spare tire support blocks 170 are made of elastic materials, such as rubber, silicone or springs. Three through holes 1111a are correspondingly provided on the back door outer panel assembly 111 for the spare tire support blocks 170 to extend out. The spare tire support blocks 170 extend outward through the through holes 1111a to form a triangular support structure. When the spare tire 160 vibrates, the three elastic spare tire support blocks 170 first reduce and filter the vibration energy of the spare tire 160, and the remaining vibration energy is transmitted to the closed cavity 112a structure of the back door inner panel assembly 112 through several installation points of the spare tire bracket 161, which fully reduces and absorbs the vibration energy. It can be understood that for a side-opening tailgate without a spare tire 160, the spare tire support block 170 may not be provided, and the corresponding back door outer panel assembly 111 does not need to be provided with through holes 1111a.

[0094] To improve the installation strength of the spare tire support block 170, refer to Fig.18 In some embodiments, the middle reinforcement unit 1123 further includes a mounting bracket 11237, and the three spare tire support blocks 170 are respectively mounted at the connection between the upper reinforcement beam 11231 and the left reinforcement beam 11233, the connection between the upper reinforcement beam 11231 and the right reinforcement beam 11234, and the mounting bracket 11237. Further, in some embodiments, the material strength and / or thickness of the mounting bracket 11237 are greater than the nut plate 11243, and the material and thickness of the mounting bracket 11237 and the upper reinforcement beam 11231, the left reinforcement beam 11233, and the right reinforcement beam 11234 can be consistent, so that the structural strength of the installation locations of the three spare tire support blocks 170 is the same.

[0095] The side opening back door 100 of the present application is connected with Figure 1 The side-opening back door 100 in the related art is subjected to a vibration test. Through the verification test, the side-opening back door 100 of the present application improves the vibration problem of the spare tire 160 by 77%, which is a significant effect. The specific test results are shown in the following table:

[0096] In summary, the side-opening back door 100 provided by the present application adopts a block welding structure for the panel structure at the taillight, and adds structural adhesive connections between the back door inner panel 1121, the door lock reinforcement plate 11222, and the hinge reinforcement plate 11242, which completely solves the adverse effect on the strength caused by the taillight interrupting the back door panel structure. The right taillight installation structure cooperates with the middle reinforcement unit 1123 and the hinge reinforcement 1124, adopts a closed cavity reinforcement structure, and realizes the left and right and upper and lower connections of the structure through welding, especially strengthening the structural performance near the upper hinge 141, specifically, the support overlap of the cavity structure of the upper reinforcement beam 11231 and the hinge installation surface of the back door inner panel 1121, so that the cavity structure here is enlarged, which greatly improves the structural performance. The reinforcement structure of the back door inner panel assembly 112 can be integrated with different material thicknesses and materials, which reduces the assembly weight and parts cost, greatly saves the working space and fixture costs of the welding process, improves production efficiency, and reduces the difficulty of production operations. The side-opening back door 100 provided in the present application can not only meet the requirements of taillight assembly, but also can be installed with a spare tire 160, has excellent anti-sinking performance and extreme off-road performance, and can meet the needs of outdoor off-road and urban outings at the same time.

[0097] A second aspect embodiment of the present application provides a vehicle, comprising a vehicle body and a side-opening tailgate 100 of any embodiment of the first aspect above, a luggage compartment is provided at the rear of the vehicle body, the side-opening tailgate 100 is hinged to the vehicle body by a hinge assembly 140, and the opening of the luggage compartment is sealed by a sealing strip 120, and the vehicle body is provided with a lock seat that locks with a door lock 130 of the side-opening tailgate 100.

[0098] For the embodiment in which the side-opening tailgate 100 is provided with a limiting structure 190, the vehicle body is provided with a limiting groove cooperating with the limiting structure 190. After the door lock 130 is locked, the limiting block of the limiting structure 190 extends into the limiting groove and snaps into place, thereby preventing the tailgate from sinking in the Z direction and rotating backward in the X direction.

[0099] The vehicle may be an SUV, MPV or off-road vehicle, and the specific model is not limited. Other undetailed structures of the vehicle may refer to the relevant disclosures of the prior art, and will not be described here.

[0100] Since the vehicle is equipped with the side-opening back door 100, the following beneficial effects are achieved accordingly:

[0101] (1) The taillights of the vehicle are completely arranged on the side-opening back door 100. The problem of taillight arrangement of the side-opening back door 100 is solved by staggering the overlapping taillight arrangement structure. The left taillight optimizes the arrangement position of the sealing strip 120 and reduces the overlap between the sealing strip 120 and the door lock 130 in the front-to-back direction, so that the taillight and the door lock 130 are arranged side by side in the front-to-back direction, thereby ensuring the realization of the taillight function. After the position of the sealing strip 120 is adjusted, the opening size of the luggage compartment is increased, which is more convenient for placing luggage. The right taillight optimizes the hinge position, enlarges the upper panel cavity 112a, and improves the structural performance. The cavity 112a structure at the lower right corner of the back door window frame 11211 is increased, which not only meets the assembly requirements of the right taillight and the uppermost hinge on the right, but also strengthens the structural strength of the uppermost hinge installation on the right, providing good anti-sinking performance and extreme off-road performance for installing the spare tire 160.

[0102] (2) The side-opening tailgate of the vehicle adopts a closed annular cavity 112a structure. During off-road and bad road driving, the spare tire 160 drives the back door to vibrate, and the vibration of the spare tire 160 is dispersed and transmitted by the frame structure 11236. The upper reinforcing beam 11231 connects the upper hinge 141 installation structure and the window frame 11211, which can better enhance the installation performance of the hinge. The cavity 112a structure absorbs vibration and reduces amplitude, avoiding vibration deformation from being transmitted to the upper weak point of the window frame 11211, thereby improving road durability. In addition, the several reinforcing structures in the back door inner panel assembly 112 all adopt a segmented welded closed structure, which can adopt different material thicknesses and materials, reducing the weight and cost of the structure, greatly saving the working space and fixture costs of the welding process, improving production efficiency, and reducing the difficulty of production operations.

[0103] (3) For the vehicle with spare tire 160, three rubber blocks are arranged on the side-opening back door 100 to form a triangular stable support structure, and the three rubber blocks can be in compression contact with the spare tire 160. The rubber blocks are installed on the closed cavity 112a structure. When the spare tire 160 vibrates, the triangularly distributed rubber blocks first reduce the vibration amplitude of the spare tire 160 and filter part of the vibration energy. The remaining vibration and energy are transmitted to the closed cavity 112a structure through the installation point of the spare tire bracket 161, which fully reduces and absorbs the vibration energy, enhances the extreme off-road performance of the off-road vehicle, and improves the riding comfort of customers.
