[0037] At present, vehicles have been widely popularized in ordinary families and integrated into people's daily lives, and people use vehicles for travel more and more frequently. The back door is a structure on the vehicle used to cover the vehicle trunk, also known as the trunk cover.

[0038] In the related art, a locking assembly is arranged between the back door of the vehicle and the vehicle body to achieve locking of the back door and the vehicle body. The locking assembly includes a lock buckle and a lock body, one of which is arranged at the bottom of the back door and located in the middle of the back door in the left-right direction of the vehicle, and the other is arranged at the bottom of the vehicle body door opening and located in the middle of the vehicle body door opening in the left-right direction of the vehicle. However, the above arrangement makes the locking stability of the lock buckle and the lock body not good enough, and there is a risk of accidental opening of the back door.

[0039] Based on the above problems, an embodiment of the present application proposes a vehicle to improve the stability and reliability of closing the vehicle's tailgate.

[0040] like Figures 1 to 5 As shown, the vehicle 10 includes a vehicle body 11, a first back door 12, and at least two first back door lock assemblies 13. The vehicle body 11 includes a vehicle body side 120. The first back door 12 is movably connected to the vehicle body 11. When the first back door 12 is closed, at least two first back door lock assemblies 13 are distributed on both sides of the first back door 12 along a first direction, and the first direction is the left and right direction of the vehicle body 11. Each first back door lock assembly 13 includes a first lock body 13a and a first lock buckle 13b, one of the first lock body 13a and the first lock buckle 13b is set on the vehicle body side 120, and the other is set on the first back door 12, and the first lock body 13a and the first lock buckle 13b can be locked with each other.

[0041] The vehicle 10 of the present application includes a body 11, a first back door 12, and a first back door lock assembly 13. The body 11 is the main structure of the vehicle 10, and the body 11 includes a body side 120. Figure 1As shown, generally, the vehicle body 11 further includes a vehicle body roof 110 located at the top of the vehicle body side 120 and a vehicle body rear 130 located behind the vehicle body side 120. A back door opening 11a is provided at the rear of the vehicle body 11, and the first back door 12 is provided at the back door opening 11a in a switchable manner. The rear of the vehicle body roof 110, the rear of the vehicle body side 120 and the vehicle body rear 130 respectively constitute the upper edge, the side edge and the bottom of the back door opening 11a. When the first back door 12 is closed, the first back door 12 seals at least part of the back door opening 11a.

[0042] The first back door 12 is rotatably connected to the vehicle body 11, and the specific connection position may be the vehicle body roof 110 or the vehicle body side 120. Undoubtedly, the first back door 12 and the vehicle body 11 may be rotated and supported by a hinge and a strut in the prior art, or by a four-link hinge in combination with a strut in the prior art. The strut in the prior art is a rod-shaped driving device that can be extended and shortened. Specifically, one end of the strut is rotatably connected to the vehicle body 11, and the other end is rotatably connected to the first back door 12. When the length of the strut changes, it can drive the first back door 12 to move.

[0043] It is understandable that each first back door lock assembly 13 includes a first lock body 13a and a first lock catch 13b, that is, the number of the first lock body 13a and the first lock catch 13b is at least two, and the first lock body 13a and the first lock catch 13b are in a one-to-one correspondence. Among them, each first lock body 13a is arranged on the body side 120 or the first back door 12, and each first lock catch 13b is also arranged on the body side 120 or the first back door 12. Of course, in a pair of first lock bodies 13a and first lock catches 13b, the first lock body 13a and the first lock catch 13b are arranged on different structures. For example, if the first lock body 13a is arranged on the body side 120, then the first lock mouth 13b is arranged on the first back door 12, and vice versa.

[0044] In the present application, at least two first back door lock assemblies 13 are provided. Moreover, when the first back door 12 is closed, at least two first back door lock assemblies 13 are distributed on both sides of the first back door 12 along the first direction. Furthermore, one of the first lock body 13a and the first lock buckle 13b of each first back door lock assembly 13 is provided on the vehicle body side 120, and the other is provided on the first back door 12. In this way, the left side of the first back door 12 and the left side of the vehicle body side 120 are locked by the first back door lock assembly 13, and the right side of the first back door 12 and the right side of the vehicle body side 120 are also locked by the first back door lock assembly 13. In this way, both sides of the first back door 12 are locked with the vehicle body 11 by the first back door lock assembly 13, which is conducive to reducing the probability of the first back door 12 being accidentally opened, and further conducive to improving the stability and reliability of the locking of the first back door 12.

[0045] In some embodiments, Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the vehicle 10 further includes a second back door 14 and at least two second back door lock assemblies 15. The second back door 14 is movably connected to the vehicle body 11 and is located below the first back door 12. When the second back door 14 is closed, at least two second back door lock assemblies 15 are distributed on both sides of the second back door 14 along the first direction. Each second back door lock assembly 15 includes a second lock body 15a and a second lock catch 15b. One of the second lock body 15a and the second lock catch 15b is disposed on the second back door 14, and the other is disposed on the rear wall 130 of the vehicle body. The second lock body 15a and the second lock catch 15b can be locked to each other.

[0046] The second back door 14 is rotatably connected to the vehicle body 11. Undoubtedly, the second back door 14 and the vehicle body 11 can be rotated and supported by hinges and struts in the prior art. Specifically, one end of the strut is rotatably connected to the vehicle body 11, and the other end is rotatably connected to the second back door 14. When the length of the strut changes, the second back door 14 can be driven to move.

[0047] In this embodiment, the vehicle 10 further includes a second back door 14 and at least two second back door lock assemblies 15. When the second back door 14 is open, the lifting height of the articles when loading and unloading the articles can be reduced, so that the process of loading and unloading the articles can be more labor-saving. There are at least two second back door lock assemblies 15, and when the second back door 14 is closed, at least two second back door lock assemblies 15 are distributed on both sides of the second back door 14 along the first direction. Further, one of the second lock body 15a and the second lock buckle 15b of each second back door lock assembly 15 is arranged on the second back door 14, and the other is arranged on the rear wall 130 of the vehicle body. In this way, on the first hand, the second back door 14 and the vehicle body 11 can be locked on the left and right sides of the second back door 14, reducing the probability of the second back door 14 being accidentally opened, thereby facilitating the stability of the locking of the second back door 14, and further facilitating the stability and reliability of the back door closure of the vehicle 10. On the second aspect, by providing the first back door lock assembly 13 and the second back door lock assembly 15, the first back door 12 and the second back door 14 can be locked relative to the vehicle body 11. For example, when only small items need to be loaded and unloaded, the first back door 12 can be closed and the second back door 14 can be opened. For another example, when goods and commodities need to be displayed, the first back door 12 can be opened and the second back door 14 can be opened or closed. In this way, it is helpful to increase the diversity of the forms of the first back door 12 and the second back door 14 to meet the needs of the trunk of the vehicle 10 under different functions.

[0048] It can be understood that each second back door lock assembly 15 includes a second lock body 15a and a second lock catch 15b, that is, the number of the second lock bodies 15a and the second lock catch 15b is at least two, and the second lock bodies 15a and the second lock catch 15b are in a one-to-one correspondence. Among them, each second lock body 15a is arranged on the second back door 14 or the rear wall 130 of the vehicle body, and each second lock catch 15b is also arranged on the second back door 14 or the rear wall 130 of the vehicle body. Of course, in a pair of second lock bodies 15a and second lock catch 15b, the second lock body 15a and the second lock catch 15b are arranged on different structures. For example, if the second lock body 15a is arranged on the second back door 14, then the second lock catch 15b is arranged on the rear wall 130 of the vehicle body, and vice versa.

[0049] It is easy to understand that in other embodiments, if the vehicle 10 has only one first back door (not shown), at least two first back door lock assemblies 13 may be provided, wherein one of the first lock body 13a and the first lock catch 13b of each first back door lock assembly 13 is provided on the vehicle body side 120, and the other is provided on the first back door 12. In this way, the probability of the first back door 12 being opened accidentally can be reduced, thereby facilitating the stability and reliability of locking the first back door 12 of the vehicle.

[0050] In some embodiments, there are two first back door lock assemblies 13, and when the first back door 12 is closed, the two first back door lock assemblies 13 are distributed on both sides of the first back door 12 along the first direction. In this way, the stability and reliability of locking the first back door 12 can be improved, and the cost of setting the first back door lock assembly 13 can also be reduced.

[0051] In some embodiments, there are two second back door lock assemblies 15, and when the second back door 14 is closed, the two second back door lock assemblies 15 are distributed on both sides of the second back door 14 along the first direction. In this way, the stability and reliability of locking the second back door 14 can be improved, and the cost of setting the second back door lock assembly 15 can also be reduced.

[0052] In some embodiments, Figures 1 to 3 As shown, the vehicle body 11 further includes a vehicle body roof 110, and the first back door 12 includes a door top cover 12a, a door side panel 12b, and a door tail plate 12c, wherein the door top cover 12a, the door side panel 12b, and the door tail plate 12c are connected in pairs, the door tail plate 12c is located at one end of the door top cover 12a along the second direction, and the door side panel 12b is located at the end of the door top cover 12a along the first direction, and the second direction is the front-rear direction of the vehicle body 11. When the first back door 12 is in a closed state, the door top cover 12a is flush with the vehicle body roof 110, and the first lock body 13a is disposed at the bottom of the door side panel 12b.

[0053] In this embodiment, each first lock body 13a is arranged on the first back door 12, so that each first lock buckle 13b is located on the body side 120. Further, this embodiment also proposes a specific position of the first lock body 13a on the first back door 12. The first back door 12 includes a door top cover 12a, a door side 12b and a door tail plate 12c. When the first back door 12 is in a closed state, the door top cover 12a is flush with the body top cover 110. In other words, the structure of the first back door 12 in the present application is different from the structure of the back door in the related art. Specifically, in addition to the door tail plate 12c at the rear, the first back door 12 in the present application also has a door top cover 12a connected to the door tail plate 12c and door side 12b located on both sides of the door top cover 12a. In this application, a part of the body side structure in the related art, such as the D-pillar, the part between the D-pillar and the C-pillar, etc., is also incorporated into the first back door 12. In this way, the back door opening 11a of the body 11 is larger. When the first back door 12 is opened, the volume of the trunk space at the rear of the vehicle 10 and the size in the first direction are larger, which is beneficial to improving the application scenarios of the trunk at the rear of the vehicle 10 and the first back door 12, and is beneficial to reducing the difficulty of loading and unloading items.

[0054] For example, the trunk and the first back door 12 can be used as a commodity display rack. When the first back door 12 is in an open state, the commodities for display can be placed in the trunk and hung on the inner side of the door top cover 12a and / or the door side 12b. In this way, sufficient commodity display space can be obtained. For stall owners in morning markets and night markets, the vehicle 10 can simultaneously meet the multiple needs of transporting commodities and displaying commodities. For another example, the trunk space can be used as a place for people to lie down and rest. In this way, it is conducive to improving the functional diversity of the trunk of the vehicle 10.

[0055] Since the first back door 12 in this embodiment includes a door top cover 12a, a door side panel 12b and a door tail panel 12c, the overall volume is relatively large. When the first back door 12 is in a closed state, the bottom of the door side panel 12b can abut against the vehicle body side panel 120, so each first lock body 13a is arranged at the bottom of the door side panel 12b, and accordingly, the first lock buckle 13b corresponding to each first lock body 13a is arranged at a position on the vehicle body side panel 120 abutting against the door side panel 12b, so that the first lock body 13a and the corresponding first lock buckle 13b can be locked to each other more firmly.

[0056] In some embodiments, Figure 2 , Figure 3 and Figure 7 As shown, the door side panel 12b includes an interior panel 121, a door side panel outer panel 122 and a first flange 123 arranged at the bottom of the interior panel 121, the interior panel 121 is located on the inner side of the door side panel outer panel 122, the bottom of the door side panel outer panel 122 is connected to the interior panel 121 through the first flange 123, and one end of the interior panel 121 close to the door tail panel 12c protrudes toward the side away from the door side panel outer panel 122 to form an accommodating cavity 124 for accommodating the first lock body 13a between the door side panel outer panel 122, the first flange 123 and the interior panel 121.

[0057] The present embodiment further proposes a specific position where the first lock body 13a is set on the door side panel 12b. The door side panel 12b includes an interior trim panel 121, a door side panel outer panel 122 and a first flange 123. The interior trim panel 121 and the door side panel outer panel 122 constitute the main structure of the door side panel 12b. The two can be sheet metal parts, for example. The interior trim panel 121 is located on the inner side of the door side panel outer panel 122, and the inner side refers to the side close to the interior space of the vehicle. The first flange 123 is located at the bottom of the interior trim panel 121. Such a setting is conducive to improving the convenience of connecting the interior trim panel 121 and the bottom of the door side panel outer panel 122. For example, they can be connected to each other by riveting, screw connection, etc. Further, as Figure 2 and Figure 3 Shown and referenced Figure 7, one end of the interior panel 121 close to the door tail plate 12c, that is, the rear part of the interior panel 121, is raised toward the side away from the door side outer panel 122. In this way, a receiving cavity 124 can be formed between the rear part of the door side outer panel 122, the first flange 123 and the rear part of the interior panel 121. In this way, the first lock body 13a can be arranged in the receiving cavity 124 and connected to the first flange 123. On the one hand, the invisible design of the first lock body 13a can be realized, and the first lock body 13a will not be exposed to the outside, which is conducive to improving the aesthetics of the appearance of the first back door 12. On the other hand, the receiving cavity 124 is located at one end of the interior panel 121 close to the door tail plate 12c, so that the first lock body 13a is as far away from the active position of the first back door 12 and the vehicle body 11 as possible, which is conducive to further improving the stability and reliability of the locking of the first back door 12, and then to improve the stability and reliability of the closing of the back door of the vehicle 10.

[0058] It should be noted that there are two door side panels 12b and the door side panels 12b are located at both ends of the door top cover 12a along the first direction. Therefore, each door side panel 12b is formed with an accommodating cavity 124. In this way, all the first lock bodies 13a in at least two first rear door lock assemblies 13 can be respectively arranged in the two accommodating cavities 124, thereby realizing the invisible design of all the first lock bodies 13a.

[0059] In some embodiments, Figure 4 , Figure 5 , Figure 8 and Fig. 9 As shown, the vehicle body side panel 120 includes a side panel outer panel 1202 and a water trough 1203. The water trough 1203 includes a water trough body 1203a and a second flange 1203b arranged on the side of the water trough body 1203a close to the side panel outer panel 1202. The water trough body 1203a is connected to the top of the side panel outer panel 1202 through the second flange 1203b. The first lock buckle 13b is arranged at one end of the second flange 1203b close to the vehicle body rear panel 130.

[0060] In this embodiment, each first lock buckle 13b is located on the vehicle body side 120, and this embodiment also proposes a specific position where the first lock buckle 13b is set on the vehicle body side 120. The vehicle body side 120 includes a side outer panel 1202 and a water trough 1203. The side outer panel 1202 can be, for example, a sheet metal part. The water trough 1203 refers to a structural member of the vehicle body side 120 for draining and guiding water. The water trough 1203 includes a water trough body 1203a and a second flange 1203b. The water trough body 1203a is the main structure of the water trough 1203 for draining and guiding water, and the water trough body 1203a can be, for example, in the shape of a groove. One side of the water trough body 1203a is connected to the top of the side outer panel 1202 through the second flange 1203b, and the connection can be achieved by, for example, welding, bolt connection, rivet connection, etc. In this way, the water trough 1203 can be fixed to the top of the side outer panel 1202. The second flange 1203b is provided to facilitate the connection between the side outer panel 1202 and the water channel 1203. Furthermore, the first lock catch 13b is provided at one end of the second flange 1203b close to the rear body 130, that is, the first lock catch 13b is provided at the tail of the second flange 1203b, so that the first lock catch 13b is as far away from the active position of the first back door 12 and the body 11 as possible, which is conducive to further improving the stability and reliability of the locking of the first back door 12, and further improving the stability and reliability of the back door closure of the vehicle 10.

[0061] It should be noted that, since the vehicle body includes a left side and a right side, and each side is provided with a water flow groove 1203. Therefore, there are two water flow grooves 1203, which are symmetrically distributed in the left and right directions of the vehicle. Each water flow groove 1203 is formed with a second flange 1203b. In this way, all the first lock buckles 13b in at least two first back door lock assemblies 13 can be arranged on the second flanges 1203b of the two water flow grooves 1203, respectively.

[0062] In some embodiments, Figure 8 and Fig. 9As shown, the body side 120 also includes a side inner panel 1201, which is located on the side of the water channel 1203 away from the side outer panel 1202. The water channel 1203 also includes a third flange 1203c provided on the side of the water channel body 1203a close to the side inner panel 1201, and the water channel body 1203a is connected to the top of the side inner panel 1201 through the third flange 1203c. The side inner panel 1201 can also be a sheet metal part, and the side inner panel 1201 can further strengthen the strength of the body side 120. The other side of the water channel body 1203a is connected to the top of the side inner panel 1201 through the third flange 1203c, for example, the connection can be achieved by welding, bolt connection, rivet connection, etc. In this way, the water channel 1203 can be fixed between the top of the side outer panel 1202 and the top of the side inner panel 1201, which can improve the convenience of connecting the water channel 1203 with the vehicle body side panel 120 on the one hand, and improve the reliability and stability of the fixing of the water channel 1203 on the other hand. Figure 2 When the first rear door 12 is closed, the bottom and front of the door side panel 12b can be crimped with the water channel 1203.

[0063] In some embodiments, Figure 4 , Figure 8 and Fig. 9 As shown, the body side 120 further includes a sealing strip 1204. The sealing strip 1204 is coated on the connection position between the side inner panel 1201 and the water flow channel 1203. Thus, on the one hand, the sealing strip 1204 can improve the sealing performance between the first back door 12 and the back door opening 11a. On the other hand, the sealing strip 1204 can also shield the connection position between the side inner panel 1201 and the water flow channel 1203, thereby facilitating the improvement of the appearance of the water flow channel 1203.

[0064] In some embodiments, Figure 1 , Figure 2 and Figure 6 As shown, the rear panel 130 of the vehicle body includes a rear panel outer panel 1301, and the rear panel outer panel 1301 includes a first sub-panel 1301a extending along a first direction and a second sub-panel 1301b located on both sides of the first sub-panel 1301a in the first direction. The height of the first sub-panel 1301a is less than the height of the second sub-panel 1301b, and the second lock buckle 15b is arranged on a side surface of the second sub-panel 1301b away from the vehicle body side panel 120.

[0065] In the present embodiment, each second lock buckle 15b is arranged on the rear body 130, and the present embodiment also proposes a specific position where the second lock buckle 15b is arranged on the rear body 130. The rear body 130 includes a rear body outer panel 1301, which can be a sheet metal part, and can be connected to the side body outer panel 1202 by welding, so that the outer panel of the body side 120 and the outer panel of the body rear 130 are fixedly connected. The rear body outer panel 1301 includes a first sub-panel 1301a and a second sub-panel 1301b. The height of the second sub-panel 1301b is higher than the height of the first sub-panel 1301a. That is, the second sub-panel 1301b extends toward the top direction close to the body side 120. Optionally, as Figure 2 As shown, one end of the second sub-plate 1301 b can extend to a position close to the water flow trough 1203 , and the second sub-plate 1301 b is connected to the tail of the water flow trough 1203 .

[0066] The second sub-plates 1301b are located on both sides of the first sub-plate 1301a in the first direction, that is, there are two second sub-plates 1301b. Moreover, all the second lock buckles 15b in at least two second back door lock assemblies 15 can be respectively arranged on the side surfaces of the two second sub-plates 1301b away from the vehicle body side 120. Such arrangement can improve the reliability and stability of the locking of the second back door 14 on the first aspect, and can also improve the convenience of the arrangement of the second lock buckles 15b on the second aspect.

[0067] In some embodiments, Figure 1 and Figure 2 As shown, the second back door 14 is hinged to the first sub-plate 1301a, and the second lock body 15a is arranged on the side of the second back door 14 along the first direction. In this embodiment, the second back door 14 is hinged to the first sub-plate 1301a, so that the second back door 14 can be rotated relative to the rear outer plate 1301, thereby closing or opening the second back door 14. Each second lock body 15a is arranged on the side of the second back door 14 along the first direction. That is, all the second lock bodies 15a in at least two second back door lock assemblies 15 can be respectively arranged on both sides of the second back door 14 along the first direction. When the second back door 14 is closed, the second lock body 15a can be locked with the second lock buckle 15b, thereby locking the second back door 14 and the rear enclosure 130 of the vehicle body.

[0068] In some embodiments, Figure 2As shown, the second lock buckle 15b is located at the middle position of the second sub-plate 1301b in the height direction of the vehicle body 11, or the second lock buckle 15b is higher than the middle position of the second sub-plate 1301b in the height direction of the vehicle body 11. In this way, the second lock buckle 15b can be located away from the hinge position of the second back door 14 and the first sub-plate 1301a, which is conducive to further improving the stability and stability of the locking of the second back door 14, and further conducive to improving the reliability and stability of the back door closure of the vehicle 10.

[0069] In some embodiments, Figure 1 As shown, when the first back door 12 is in the closed state, the top of the second back door 14 is butted against the bottom of the tail plate 12c. In this way, when the first back door 12 and the second back door 14 are both locked with the vehicle body 11, the first back door 12 and the second back door 14 can seal the back door opening 11a of the vehicle, which is beneficial to improve the sealing performance of the vehicle trunk.
