[0033] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0034] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0035] In the related art, a vehicle includes a body and a tailgate rotatably connected to the body. The tailgate can be closed or opened relative to the body, and the tailgate flips upward relative to the body during the opening process. When a user takes or puts items in the trunk, the tailgate needs to be opened as a whole.

[0036] However, in certain usage scenarios, the space behind the vehicle is small, so the back door cannot be fully opened, which makes it difficult for users to take and put items in the trunk, resulting in poor overall vehicle performance.

[0037] Therefore, an embodiment of the present application provides a vehicle, which improves the structure of the vehicle's rear door so that when the rear space of the vehicle is relatively narrow, the user can also take and put items in the trunk, thereby making the vehicle provided by the embodiment of the present application have better performance.

[0038] The embodiments of the present application will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0039] See also Figures 1 to 3 , Figure 1 A schematic diagram of a first partial structure of a vehicle provided in an embodiment of the present application, Figure 2 for Figure 1 Schematic diagram of the plane structure from another perspective. Figure 3 The three-dimensional structure diagram of the partial structure of the vehicle body in the embodiment of the present application is shown in the figure. As shown in the figure, the present embodiment provides a vehicle, including a vehicle body 1, two door glasses 2 and a back door 3.

[0040] Among them, the vehicle body 1 includes a vehicle body 11, in which a driving space and a trunk space are formed. The rear end of the vehicle body 11 is provided with two tailgate trims 12 arranged opposite to each other along the width direction of the vehicle body 1, and a first opening 13 is formed between the two tailgate trims 12, and a second opening 14 is formed below the two tailgate trims 12. That is to say, the first opening 13 is located above the second opening 14, and the first opening 13 and the second opening 14 are connected in the up and down directions.

[0041] It should be noted that the width direction of the vehicle body 1 is Figures 1 to 3 The yy-axis direction is consistent.

[0042] The two door glasses 2 are arranged at the first opening 13, and the two door glasses 2 are arranged along the width direction of the vehicle body 1. One side of each door glass 2 close to the side of the vehicle body 1 is rotatably connected to the vehicle body 1 to open or close the door glass 2 and open or close the first opening 13. The opening of the first opening 13 can be understood as partially opening or fully opening. Partial opening refers to a state in which one door glass 2 is open and the other door glass 2 is closed, and fully opening refers to a state in which both door glasses 2 are open.

[0043] It is not difficult to understand that the side of the vehicle body 1 mentioned above refers to the left and right sides of the vehicle body 1 along its width direction. Figure 1 The direction in the figure is taken as the standard, the door glass 2 located on the left side is rotatably connected to the vehicle body 1 on the left side, and the door glass 2 located on the right side is rotatably connected to the vehicle body 1 on the right side.

[0044] The rotation connection between the door glass 2 and the vehicle body 1 is the rotation connection between the door glass 2 and the vehicle body 11. Figure 4 As shown, Figure 4 The first cross-sectional view of the vehicle provided in the embodiment of the present application. Specifically, the vehicle body 11 has a vehicle frame 111, the vehicle frame 111 includes a vehicle frame inner panel 1111 and a vehicle frame outer panel 1112 connected to the outer side of the vehicle frame inner panel 1111, the outer side of the vehicle frame outer panel 1112 is connected to a vehicle frame reinforcement plate 1113, the door glass 2 is rotatably connected to the vehicle frame reinforcement plate 1113, and the back door trim panel 12 is fixedly connected to the vehicle frame reinforcement plate 1113.

[0045] Among them, the vehicle frame reinforcement plate 1113 and the door glass 2 are connected by a hinge 4, and the hinge 4 includes a fixed part 41 and a movable part 42. The fixed part 41 is arranged on the vehicle frame reinforcement plate 1113, and the movable part 42 is arranged on the door glass 2. The fixed part 41 and the movable part 42 are rotatably connected to realize the rotational connection between the vehicle frame reinforcement plate 1113 and the door glass 2.

[0046] Furthermore, the back door 3 is disposed at the second opening 14, and the back door 3 is movably connected to the frame 111 of the vehicle body 1 to open or close the back door 3 and open or close the second opening 14. That is, in the vehicle provided in this embodiment, the trunk space can be opened through the door glass 2 or through the back door 3.

[0047] In order to overcome the problem in the related art that it is inconvenient to take and put items in the trunk when the rear space of the vehicle is relatively narrow. In this embodiment, when the first opening 13 and the second opening 14 are both closed, the dimension value of the door glass 2 extending along the width direction of the vehicle body 1 is the first dimension, the dimension value of the back door 3 extending along the height direction of the vehicle body 1 is the second dimension, and the dimension value of the back door 3 extending along the width direction of the vehicle body 1 is the third dimension; the second dimension and the third dimension are both larger than the first dimension. Here, it should be noted that since the back door 3 can be opened by flipping downward or flipping sideways, the relationship between the first dimension, the second dimension and the third dimension is defined here.

[0048] In this way, the space behind the vehicle occupied when the door glass 2 is opened is smaller than the space behind the vehicle occupied when the tailgate 3 is opened. When the space behind the vehicle is smaller and the items to be taken are smaller, only the two door glasses 2 or one of the two door glasses 2 can be opened. In this way, it can be avoided to a certain extent that the items in the trunk cannot be taken due to the smaller space behind the vehicle, thereby improving the convenience of use of the vehicle provided by this embodiment and further improving the performance of the vehicle provided by this embodiment.

[0049] It should be noted that the height direction of the vehicle body 1 is Figures 1 to 3 The direction of the zz axis is consistent.

[0050] Specifically, the back door 3 is rotatably connected to the frame 111, and the rotatable connection between the frame 111 and the back door 3 is located at the bottom of the second opening 14, wherein the back door 3 and the frame 111 can also be connected together by a hinge. That is to say, in the specific implementation of this embodiment, the back door 3 is opened in the form of flipping downward. Here, the connection method between the back door 3 and the frame 111 is not specifically limited.

[0051] Please combine Figure 5 , Figure 5 This is a schematic diagram of the second partial structure of the vehicle provided in the embodiment of the present application. When the door glass 2 is in the closed state, in order to ensure the stability of the state of the door glass 2 so that the space in the trunk is closed and the sealing of the trunk space is ensured, in some embodiments, a corresponding locking structure can be provided between the door glass 2 and the vehicle frame 111 to lock the door glass 2 and the vehicle body 1 together.

[0052] The door glass 2 has a first mounting surface 21 and a second mounting surface 22 which are arranged opposite to each other. When the door glass 2 is in a closed state, the first mounting surface 21 is arranged forward, and the second mounting surface 22 is arranged backward.

[0053] In a specific implementation of this embodiment, a lock hook 5 is provided on the top of the first mounting surface 21, and a lock body 6 is provided on the vehicle body 1. The lock hook 5 and the lock body 6 can be locked together to at least partially close the first opening 13. The lock hook 5 is connected to the first mounting surface 21 through a fixing plate 7, and the fixing plate 7 can be bonded to the first mounting surface 21. The lock hook 5 includes two locking rods 51 spaced apart in the up-down direction, and a connecting rod 52 connected to the ends of the two locking rods 51 away from the fixing plate 7. In this way, when the lock hook 5 and the lock body 6 are locked together, the connecting rod 52 is restricted in the lock body 6, so that the lock hook 5 and the lock body 6 can be locked together, and then the door glass 2 and the vehicle frame 111 can be locked together.

[0054] It should be noted that the lock body 6 can be either a mechanical lock or an electronic lock.

[0055] Please combine Figure 6 and Figure 7 , Figure 6 A schematic diagram of a third partial structure of a vehicle provided in an embodiment of the present application, Figure 7 This is a schematic diagram of the structure of the fourth partial structure of the vehicle provided in the embodiment of the present application. In order to fix the two lock bodies 6, the vehicle body 11 of the vehicle body 1 has a roof 112, and the bottom of the roof 112 is connected to a fixing bracket 8, and the fixing bracket 8 is formed with a mounting groove arranged toward the rear, and the two lock bodies 6 are detachably installed in the mounting groove 81.

[0056] Specifically, the fixed bracket 8 includes a first frame body 82 and a second frame body 83 which are staggered in the front-to-back direction. The first frame body 82 includes a first connecting portion 821, a first transition portion 822 and a first extension portion 823 which are connected in sequence. The first connecting portion 821 extends in the front-to-back direction of the vehicle, and the first connecting portion 821 is connected to the ceiling 112. The first transition portion 822 is connected to the rear end of the first connecting portion 821, and the first transition portion 822 extends in the up-down direction. The first extension portion 823 is connected to the bottom end of the first transition portion 822 and extends rearward.

[0057] Among them, the first connecting part 821 and the ceiling 112 can be detachably connected together by threaded fasteners such as screws, a weight-reducing hole 8221 can be set on the first transition part 822, and a weight-reducing notch 8231 can be set on the first extension part 823. In this way, the weight of the first frame 82 can be reduced, making it easier to connect the first frame 82 to the ceiling 112.

[0058] Furthermore, the second frame 83 includes a second connecting portion 831, a second transition portion 832 and a second extension portion 833 which are connected in sequence, the second connecting portion 831 extends along the front-to-rear direction of the vehicle, is located behind the first connecting portion 821, and is connected to the ceiling 112; the second transition portion 832 is connected to the rear end of the second connecting portion 831, the second transition portion 832 is located behind the first transition portion 822, and the second transition portion 832 extends along the up-down direction; the second extension portion 833 is connected to the bottom end of the second transition portion 832 and extends forward, and the second extension portion 833 is located above the first extension portion 823, the first extension portion 823, the second extension portion 833 and the first transition portion 822 enclose the above-mentioned mounting groove 81.

[0059] The lock body 6 and the first frame 82 and the second frame 83 can be connected to the fixing bracket 8 by threaded fasteners penetrating the first extension portion 823 , the lock body 6 and the second extension portion 833 .

[0060] It is understandable that when the door glass 2 is opened to the maximum angle, if the position of the door glass 2 cannot be limited, the door glass 2 will move in the closing direction under the action of external force, which may not only cause harm to the user but also damage the door glass 2 itself.

[0061] Therefore, please combine Figure 8 , Figure 8 A schematic diagram of the fifth partial structure of the vehicle provided in the embodiment of the present application. In some embodiments, two stoppers 9 are provided on the vehicle body 1, and the two stoppers 9 are provided one-to-one with the two door glasses 2, and the stoppers 9 are connected to the first mounting surface 21; when the door glasses 2 are opened, the first mounting surface 21 is provided toward the side of the vehicle body 1, and the stoppers 9 are separated from the first mounting surface 21.

[0062] Specifically, one end of the stopper 9 is connected to the corresponding back door trim 12, such as Figure 8 As shown, an adapter plate 15 is provided on the back door trim 12 for one end of the limiter 9 to pass through and is rotatably connected to the limiter 9 .

[0063] A buckle 10 is provided on the first mounting surface 21 , and when the door glass 2 is closed, the stopper 9 is engaged and connected with the buckle 10 .

[0064] As for the specific clamping method between the end of the limiter 9 and the buckle 10, a clamping section 91 is formed at the end of the limiter 9, and limiting plates 92 with a larger diameter than the clamping section 91 are arranged at both ends of the clamping section 91, and the buckle 10 includes a fixed plate 101 connected to the first mounting surface 21, and a clamping portion 102 is arranged at the end of the fixed plate 101 facing away from the first mounting surface 21, and a clamping groove 103 for the clamping section 91 to be clamped is formed on the clamping portion 102, and in order to facilitate the clamping of the clamping section 91 into the clamping groove 103, two relatively arranged outward expansion portions 104 are arranged at the end of the clamping portion 102 facing away from the fixed plate 101, and the opening of the clamping groove 103 is made larger by the arrangement of the two outward expansion portions 104, so that the clamping section 91 can be clamped into the clamping groove 103 for easy use.

[0065] It should be noted that, in the axial direction of the clamping section 91 , the clamping groove 103 passes through the clamping portion 102 .

[0066] In some embodiments, in order to facilitate opening and closing of the door glass 2, an operating handle 20 is provided on the second mounting surface 22. By providing the operating handle 20, when opening or closing the door glass 2, the operating handle 20 can be held by hand, and force can be applied to the operating handle 20 to open or close the door glass 2.

[0067] In order to improve the appearance of the vehicle provided by this embodiment, in a specific implementation of this embodiment, the vehicle body 1 has a central axis extending in the height direction of the vehicle body 1, and the two door glasses 2 are arranged axially symmetrically about the central axis. In this way, not only can the appearance of the vehicle be improved, but also, when the door glasses 2 are opened, the occupied dimension of the door glasses 2 in the front-rear direction of the vehicle is at most one-half of the first opening 13 in the width direction of the vehicle, thereby, to a certain extent, avoiding the large occupied dimension of the door glasses 2 and interference with obstacles in the environment where the vehicle is located, and further improving the convenience of users in taking and putting items in the trunk.

[0068] Please combine Figure 2 and Figure 5It can be understood that when both door glasses 2 are in a closed state, if there is a gap between the two door glasses 2, dust and liquid from the outside will enter the interior of the vehicle through the gap. In order to avoid this phenomenon to a certain extent, in the specific implementation of this embodiment, a sealing strip 30 is provided on one of the two door glasses 2; when both door glasses 2 are closed, the sealing strip 30 is located between the two door glasses 2, and the sealing strip 30 is pressed against the other of the two door glasses 2. In this way, when both door glasses 2 are closed, the gap between the two door glasses 2 can be sealed by the provision of the sealing strip 30, so as to avoid liquid and dust from the outside from entering the interior of the vehicle to a certain extent, so that the overall sealing performance of the vehicle provided by this embodiment is good.

[0069] It should be noted that the connection method between the sealing strip 30 and the door glass 2 can be bonding, and the connection method between the sealing strip 30 and the door glass 2 is not specifically limited.

[0070] Please combine Fig. 9 , Fig. 9 This is a second cross-sectional view of the vehicle provided in the embodiment of the present application. It is understandable that when the door glass 2 is closed, there will be a gap between the top of the door glass 2 and the top of the vehicle frame 111. Therefore, the vehicle provided in the present embodiment may further include a first glass groove 40 disposed at the top of the first opening 13. When the door glass 2 is closed, the first glass groove 40 presses against the top of the door glass 2. In this way, when both door glasses 2 are closed, the top of the door glass 2 and the vehicle frame 111 can be sealed, further improving the sealing performance of the vehicle provided in the present embodiment.

[0071] In addition, in a specific implementation of this embodiment, the vehicle further includes a second glass groove 50 disposed on the ceiling 112, the shape of the second glass groove 50 is adapted to the shape of the first opening 13, and when the door glass 2 is closed, the second glass groove 50 is pressed against the first mounting surface 21. In this way, the door glass 2 and the vehicle body 11 can be sealed for a second time, thereby improving the sealing performance of the vehicle provided by this embodiment.

[0072] Specifically, the ceiling 112 has a ceiling inner panel 1121 and a ceiling outer panel 1122 , the first connecting portion 821 and the second connecting portion 831 are both connected to the ceiling outer panel 1122 , the first glass groove 40 is crimped to the ceiling inner panel 1121 , and the ceiling inner panel 1121 is located on the side close to the door glass 2 .

[0073] It should be noted that, in this embodiment, the front-to-back direction of the vehicle is the length direction of the vehicle body 1, the up-down direction is the height direction of the vehicle body 1, and the left-right direction of the vehicle is the width direction of the vehicle body 1. It is understandable that due to different contexts, no unified definition is used in the description of directions.

[0074] The above contents are only specific implementation methods of the present application, but the protection scope of the present application is not limited thereto.
