[0099] The present application provides a cowl door device and also provides a vehicle including the cowl door device.

[0100] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0101] like Figure 1-17 As shown, the embodiment of the present application discloses a cowl door device. Figure 1-4The cowl door assembly includes a vehicle body mounting assembly 1, an upper door assembly 2, and a lower door assembly 3. The vehicle body mounting assembly 1 includes a vehicle body frame 11. The upper door assembly 2 includes an upper door 21, which is hingedly connected to the vehicle body frame 11 and can cover the vehicle body frame 11. The lower door assembly 3 includes a lower door 31, which is hingedly connected to the upper door assembly 2 and can cover the vehicle body frame 11. The upper door 21 and the lower door 31 are fixed together so that they can flip relative to the vehicle body frame 11 and can simultaneously disconnect from the vehicle body frame 11. The lower door 31 can flip relative to the upper door 21 and disconnect from the upper door assembly 2, thereby independently disconnecting from the vehicle body frame 11.

[0102] Please see the attached Figure 1 、 4 6. The front and rear direction of the vehicle is the X direction. Please refer to the attached Figure 1 、 4 , the direction indicated by the arrow in 6; the width direction of the vehicle is the same as the width direction of the front door device, that is, the Y direction. For details, please refer to Figure 1 、 4 , the direction indicated by the arrow in 6; the height direction of the vehicle is the Z direction, please refer to the attached Figure 1 、 4 , the direction indicated by the arrow in 6.

[0103] The front and rear that appear in the following text are relative, that is, along the front-to-back direction of the vehicle (i.e., the X direction), the side closer to the front of the vehicle is the front, and the side closer to the rear of the vehicle is the rear; the top and bottom are relative, that is, along the height direction of the vehicle (i.e., the Z direction), the side closer to the roof of the vehicle is the top, and the side closer to the bottom of the vehicle is the bottom.

[0104] It should be noted that when both the upper and lower doors 21 and 31 cover the vehicle frame 11, along the X direction, both the upper and lower doors 21 and 31 are located in front of the vehicle frame 11. Figure 4 When both the upper flip door 21 and the lower flip door 31 cover the vehicle body frame 11 , the upper flip door 21 and the lower flip door 31 are arranged upward and downward along Z, and the bottom of the upper flip door 21 is butted against the top of the lower flip door 31 .

[0105] The present application separates the hinge axis connecting the upper flip door 21 and the hinge axis connecting the lower flip door 31. The upper flip door 21 is hinged to the vehicle body frame 11, and the lower flip door 31 is hinged to the upper flip door assembly 2. In this way, when the lower flip door 31 is installed, the hinge axis used by the lower flip door 31 can be freely adjusted in position, rather than having to be coaxially arranged with the hinge axis used by the upper flip door 21. This facilitates adjustment of the gap between the upper flip door 21 and the lower flip door 31. In addition, by flipping the upper flip door 21, the upper flip door 21 can be switched between covering and uncovering the vehicle body frame 11; by flipping the lower flip door 31, the lower flip door 31 can be switched between covering and uncovering the vehicle body frame 11. The assembly connection is reliable and easy to operate.

[0106] Furthermore, since the lower flip door 31 is not directly hinged to the vehicle body frame 11 but is hinged to the upper flip door assembly 2, the lower flip door 31 can be locked and fixed to the upper flip door assembly 2, so that the lower flip door 31 and the upper flip door 21 are fixed as a whole, and both can be flipped synchronously relative to the vehicle body frame 11. Of course, the lower flip door 31 can also be released from the lock on the upper flip door assembly 2, so that the lower flip door 31 can be flipped independently relative to the upper flip door 21. As described above, the flipping scenarios of the upper flip door 21 and the lower flip door 31 are enriched, and ultimately at least the following flipping scenarios can be realized:

[0107] ①Please refer to the attached Figure 7 , the upper flip door 21 and the lower flip door 31 are flipped as a whole relative to the vehicle body frame 11;

[0108] ②Please refer to the attached Figure 8 , the upper flip door 21 flips relative to the vehicle body frame 11, and at the same time the lower flip door 31 flips relative to the upper flip door 21;

[0109] ③Please refer to the attached Figure 9 , the lower flip door 31 flips relative to the upper flip door 21, and finally achieves the effect that the upper flip door 21 covers the vehicle body frame 11 and the lower flip door 31 flips independently relative to the vehicle body frame 11;

[0110] ④Please refer to the attached Figure 1 The upper flip door 21 and the lower flip door 31 are disassembled until they are separated from the vehicle body frame 11;

[0111] ⑤ The lower flip door 31 is independently disassembled until it is separated from the upper flip door assembly 2 , so as to achieve the effect of the lower flip door 31 being independently separated from the vehicle body frame 11 .

[0112] As described above, the problems that the upper and lower doors 21 and 31 cannot be disassembled, and the upper and lower doors 21 and 31 cannot be flipped over as a whole, and cannot be disassembled as a whole are solved, thereby meeting the application requirements in various specific scenarios; specifically: the lower door 31 can be flipped over and removed separately to facilitate connection to a trailer hook; in addition, the upper and lower doors 21 and 31 can be fixed as a whole and flipped over and removed synchronously to facilitate the inspection and maintenance of components such as wipers and defrosters inside the front door device.

[0113] In certain embodiments of the present application, the flip door assembly 2 includes a flip door frame 22, a first male hinge 23, and a first female hinge 24. Figure 2 The upper door frame 22 is connected to the upper door 21 and extends to the bottom of the lower door 31. Figure 1 、 5 -6, 10, the first male hinge 23 is fixed to the vehicle body frame 11 and is formed with a first column 231 parallel to the width direction (ie, Y direction) of the front door device. Figure 2 、 5 -6, 10-11, the first female hinge 24 is fixed to the bottom of the flip door frame 22 and forms a first surrounding portion 241 that can rotate about the first post 231. The first surrounding portion 241 has a first notch along the circumference of the first surrounding portion 241 as it rotates about the first post 231. The first notch allows the first surrounding portion 241 to be separated from the first post 231, thereby separating the flip door 21 from the vehicle body frame 11.

[0114] It should be noted that the width direction of the front door device is the same as the width direction of the vehicle, that is, the Y direction; the Y direction will be used uniformly in the following text.

[0115] Please see the attached Figure 2 The upper door frame 22 is parallel to the vehicle's height direction (i.e., the Z direction, referred to as the Z direction below). Multiple upper door frames 22 are spaced apart along the Y direction; preferably, two upper door frames 22 are provided. The upper door 21 is fixed above the upper door frames 22.

[0116] The upper door frame 22 provides the mounting point for the hinged connection of the upper door 21 to the vehicle body frame 11. Since the upper door frame 22 extends from the upper door 21 to the bottom of the lower door 31, and the first female hinge 24 is fixed to the bottom of the upper door frame 22, the first male hinge 23, which is hingedly assembled with the first female hinge 24, is also located at the bottom of the upper door frame 22. Consequently, the hinge axis of the upper door frame 22 (the same as that of the upper door 21, namely, the first post 231 of the first male hinge 23) is located at the bottom of the upper door frame 22. When the upper door 21 needs to be released from the vehicle body frame 11, the upper door frame 22 pivots forward and downward about the first post 231, thereby driving the upper door 21, mounted on the upper door frame 22, to complete its forward and downward pivoting motion.

[0117] The hinged assembly of the first male hinge 23 and the first female hinge 24 achieves the technical effect of allowing the first surrounding portion 241 to rotate about the first column 231. Since the first column 231 is parallel to the Y-axis, the rotation direction of the first surrounding portion 241 is defined, thereby defining the flip direction of the flip door frame 22 connected to the first female hinge 24, and further defining the flip direction of the flip door 21 mounted on the flip door frame 22. Specifically: along the X-direction, the first surrounding portion 241 rotates forward around the first column 231, thereby driving the up-flip door 21 to flip forward and downward (the forward and downward flipping of the up-flip door 21 is the opening flipping of the up-flip door 21), so that the up-flip door 21 releases its cover on the vehicle body frame 11 or increases the opening flipping angle of the up-flip door 21 relative to the vehicle body frame 11; along the X-direction, the first surrounding portion 241 rotates backward around the first column 231, thereby driving the up-flip door 21 to flip backward and upward (the backward and upward flipping of the up-flip door 21 is the closing flipping of the up-flip door 21), so as to reduce the opening flipping angle of the up-flip door 21 relative to the vehicle body frame 11 or make the up-flip door 21 cover the vehicle body frame 11.

[0118] Please refer to the attached Figure 10 The first surrounding portion 241 is a first U-shaped structure with a first notch; the first notch achieves the technical effect of the first surrounding portion 241 being separated from the first column 231; specifically, when the first surrounding portion 241 rotates forward a certain angle around the first column 231, thereby driving the flip door 21 to open and flip a certain angle relative to the vehicle body frame 11, the first surrounding portion 241 is rotated forward a certain angle around the first column 231, and the flip door 21 is rotated along the groove depth direction of the first U-shaped structure (the groove depth direction is the attached Figure 10 The first surrounding portion 241 is disassembled through the first notch until it is separated from the first column 231, thereby achieving the disassembly of the first female hinge 24 to be separated from the first male hinge 23, and thus achieving the disassembly of the flip door assembly 2 to be separated from the vehicle body frame 11. Figure 11, which is a structural schematic diagram of the first female hinge 24 being disassembled until it is separated from the first male hinge 23, that is, a structural schematic diagram of the up-flip door assembly 2 being disassembled until it is separated from the vehicle body frame 11.

[0119] As described above, the structure of the first surrounding portion 241 and the first column 231 is simple, and the assembly and installation are convenient and fast; and by forming a first notch in the first surrounding portion 241, the first surrounding portion 241 and the first column 231 can be disassembled quickly and easily, thereby facilitating the easy and fast disassembly of the upper flip door assembly 2 until it is separated from the vehicle body frame 11, providing operating space for the inspection and replacement of components inside the front door device.

[0120] In certain embodiments of the present application, the lower flip door assembly 3 includes a second male hinge 32 and a second female hinge 33. Figure 2 、 5 -6, 12, the second male hinge 32 is fixed to the bottom of the flip door frame 22, and is formed with a second column 321 parallel to the width direction (ie, Y direction) of the front door device. Figure 3 、 5 -6, 12-13, the second female hinge 33 is fixed to the lower flip door 31 and has a second surrounding portion 331 that can rotate about the second post 321. The second surrounding portion 331 has a second notch along the circumference of the second surrounding portion 331 as it rotates about the second post 321, so that the second surrounding portion 331 can be separated from the second post 321 through the second notch.

[0121] The upper door frame 22 provides a mounting point for the second male hinge 32. Because the second male hinge 32 is fixed to the bottom of the upper door frame 22, the second female hinge 33, which is hingedly assembled with the second male hinge 32, is also located at the bottom of the upper door frame 22. Consequently, the hinge axis of the lower door 31 (i.e., the second post 321 of the second male hinge 32) is located at the bottom of the upper door frame 22. When the lower door 31 needs to be released from the upper door frame 22, it flips forward and downward around the second post 321.

[0122] It should be noted that when the upper flip door 21 covers the vehicle body frame 11, the vehicle body frame 11 is parallel to the upper flip door frame 22; at this time, the covering or uncovering state of the lower flip door 31 relative to the upper flip door frame 22, that is, the covering or uncovering state of the lower flip door 31 relative to the vehicle body frame 11.

[0123] The hinged assembly of the second male hinge 32 and the second female hinge 33 allows the second surrounding portion 331 to rotate about the second column 321. Since the second column 321 is parallel to the Y-axis, this defines the rotational direction of the second surrounding portion 331, and thus the flipping direction of the downward-folding door 31 connected to the second female hinge 33. Specifically: along the X direction, the second surrounding portion 331 rotates forward around the second column 321, thereby driving the lower flip door 31 to flip forward and downward (the forward and downward flipping of the lower flip door 31 is the opening flipping of the lower flip door 31), so that the lower flip door 31 is released from the cover of the upper flip door frame 22 or the opening flipping angle of the lower flip door 31 relative to the upper flip door frame 22 is increased; along the X direction, the second surrounding portion 331 rotates backward around the second column 321, thereby driving the lower flip door 31 to flip backward and upward (the backward and upward flipping of the lower flip door 31 is the closing flipping of the lower flip door 31), so as to reduce the opening flipping angle of the lower flip door 31 relative to the upper flip door frame 22 or make the lower flip door 31 cover the upper flip door frame 22.

[0124] The second surrounding portion 331 is a second U-shaped structure with a second notch; the second notch achieves the technical effect of the second surrounding portion 331 being separated from the second column 321; specifically, when the second surrounding portion 331 rotates around the second column 321 by a certain angle, thereby driving the lower flip door 31 to open and flip over a certain angle relative to the upper flip door frame 22, the second U-shaped structure is formed. Figure 12 The second surrounding portion 331 is disassembled through the second notch until it is separated from the second column 321, thereby achieving the disassembly of the second female hinge 33 to separate from the second male hinge 32, and thus achieving the disassembly of the lower flip door 31 to separate from the upper flip door frame 22. Figure 13 , which is a structural schematic diagram of the second female hinge 33 being disassembled to be separated from the second male hinge 32 , that is, a structural schematic diagram of the lower flip door 31 being disassembled to be separated from the upper flip door frame 22 .

[0125] As described above, the structure of the second surrounding portion 331 and the second column 321 is simple, and the assembly and installation are convenient and fast; and by forming a second notch in the second surrounding portion 331, the second surrounding portion 331 and the second column 321 can be disassembled quickly and easily, thereby facilitating the easy and fast disassembly of the lower flip door 31 to separate it from the upper flip door frame 22, so as to facilitate the connection of the trailer hook for use.

[0126] It should be further explained that the upper door 21 must first be opened and flipped relative to the vehicle body frame 11, and then the lower door 31 must be opened and flipped relative to the upper door frame 22. If no maintenance is required and only the trailer hook is to be connected for use, the upper door 21 is closed and flipped again until it covers the vehicle body frame 11, ultimately achieving the effect of only the lower door 31 being opened and flipped relative to the vehicle body frame 11. At this time, the opening and flipping angle of the lower door 31 relative to the upper door frame 22 is the same as the opening and flipping angle of the lower door 31 relative to the vehicle body frame 11.

[0127] Please see the attached Figure 6 、 10 -11. In certain embodiments of the present application, the front door device is formed with a first limiting portion 232, and the first female hinge 24 is formed with a first limiting hook 242 to limit the rotation angle of the first surrounding portion 241 around the first column 231, so as to prevent the first surrounding portion 241 from detaching from the first column 231 through the first notch.

[0128] It should be noted that, along the X direction, when the first surrounding portion 241 rotates forward around the first column 231, the first limiting hook 242 can be limited to the first limiting portion 232. Under the obstruction of the first limiting portion 232, the first surrounding portion 241 can no longer continue to rotate forward, and the first surrounding portion 241 reaches the limit position of forward rotation (at this time, the first surrounding portion 241 drives the flip-up door 21 to reach the limit angle of opening and flipping).

[0129] Furthermore, when the first surrounding portion 241 rotates forward to the extreme position around the first column 231, the first notch can be prevented from facing upward, thereby preventing the first surrounding portion 241 from automatically falling downward along the groove depth direction (the groove depth direction is the up and down direction at this time) through the first notch and separating from the first column 231 under the action of its own gravity.

[0130] As described above, under the action of rotational force only, no matter how much the first surrounding portion 241 rotates forward around the first column 231, the first surrounding portion 241 will not automatically detach from the transmission connection with the first column 231, so the first female hinge 24 will not automatically detach from the hinged cooperation with the first male hinge 23, and the flip door 21 will not detach from the connection with the vehicle body frame 11. If it is necessary to detach the flip door 21 from the vehicle body frame 11, it is necessary to manually apply an additional pulling force along the groove depth direction of the first surrounding portion 241 (the direction of the pulling force is shown in the attached figure). Figure 10 In the direction indicated by the hollow arrow), the first surrounding portion 241 is disconnected from the first column 231 through the first notch, thereby disconnecting the first female hinge 24 from the hinged connection with the first male hinge 23, and disconnecting the flip door 21 from the vehicle body frame 11.

[0131] As can be seen from the above, during the opening and flipping action of the upper flip door 21, the upper flip door 21 will not automatically detach from the connection with the vehicle body frame 11, so that the opening and flipping angle of the upper flip door 21 can be precisely controlled; further, the disassembly action of the upper flip door 21 relative to the vehicle body frame 11 can be precisely controlled manually, and whether to disassemble the upper flip door 21 can be selected according to actual needs.

[0132] Please see the attached Figure 6 、 12 -13. In some embodiments, the front door device is formed with a second limiting portion 233, and the second female hinge 33 is formed with a second limiting hook 332 to limit the rotation angle of the second surrounding portion 331 around the second column 321 to prevent the second surrounding portion 331 from detaching from the second column 321 through the second notch.

[0133] It should be noted that, along the X direction, when the second surrounding portion 331 rotates forward around the second column 321, the second limiting hook 332 can be limited to the second limiting portion 233. Under the obstruction of the second limiting portion 233, the second surrounding portion 331 can no longer rotate forward, and the second surrounding portion 331 reaches the limit position of forward rotation (at this time, the second surrounding portion 331 drives the lower flip door 31 to reach the limit angle of opening and flipping).

[0134] Furthermore, when the second surrounding portion 331 rotates forward around the second column 321 to the extreme position, the second notch position can be prevented from facing upward, thereby preventing the second surrounding portion 331 from automatically falling downward along the groove depth direction (the groove depth direction is the up and down direction at this time) through the second notch and detaching from the second column 321 under the action of its own gravity.

[0135] As described above, under the action of rotational force only, no matter how much the second surrounding portion 331 rotates forward around the second column 321, the second surrounding portion 331 will not automatically detach from the transmission connection with the second column 321, so the second female hinge 33 will not automatically detach from the hinged assembly with the second male hinge 32, and the lower flip door 31 will not detach from the connection with the upper flip door frame 22. If the lower flip door 31 needs to be detached from the connection with the upper flip door frame 22, it is necessary to manually apply an additional pulling force along the groove depth direction of the second surrounding portion 331 (the direction of the pulling force is shown in the attached figure). Figure 12 In the direction indicated by the hollow arrow), the second surrounding portion 331 is disconnected from the second column 321 through the second notch, thereby disconnecting the second female hinge 33 from the hinged connection with the second male hinge 32, and disconnecting the lower flip door 31 from the upper flip door frame 22.

[0136] As can be seen from the above, during the opening and flipping action of the lower flip door 31, the lower flip door 31 will not automatically detach from the connection with the upper flip door frame 22, so that the opening and flipping angle of the lower flip door 31 can be precisely controlled; further, the disassembly action of the lower flip door 31 relative to the upper flip door frame 22 can be precisely controlled manually, and whether to disassemble the lower flip door 31 can be selected according to actual needs.

[0137] Please see the attached Figure 5-6 In certain embodiments of the present application, when the flip door 21 covers the vehicle body frame 11 , the first notch of the first surrounding portion 241 is positioned downward, and the first limiting hook 242 is formed at an end of the first notch away from the flip door 21 .

[0138] It should be noted that when the first notch is facing downward, along the X direction, the first notch includes a first end relatively located in the front and a second end relatively located in the rear; the end of the first notch away from the flip door 21 is the second end of the first notch.

[0139] When the flip door 21 is positioned over the vehicle body frame 11, the first stopper hook 242 extends rearwardly along the X-axis. The first stopper hook 242 rotates synchronously with the first surrounding portion 241. As the first surrounding portion 241 rotates forward about the first post 231, the first stopper hook 242 rotates upward and forward. When the first surrounding portion 241 rotates forward to its limit position, the first stopper hook 242 is precisely located within the first stopper portion 232.

[0140] As described above, the first limiting hook 242 has a simple structure and cooperates with the first surrounding portion 241 ingeniously, so as to stably and reliably limit the forward rotation angle of the first surrounding portion 241 .

[0141] Please see the attached Figure 5-6 In some embodiments, when both the upper and lower doors 21 and 31 are covered on the vehicle body frame 11 , the second notch of the second surrounding portion 331 faces downward, and the second limiting hook 332 is formed at an end of the second notch away from the lower door 31 .

[0142] It should be noted that when the second notch is facing downward, along the X direction, the second notch includes a third end relatively located in the front and a fourth end relatively located in the rear; the end of the second notch away from the downward flip door 31 is the fourth end of the second notch.

[0143] When both the upper and lower doors 21 and 31 are positioned over the vehicle body frame 11, the second stopper hook 332 extends rearwardly along the X-axis. The second stopper hook 332 rotates synchronously with the second surrounding portion 331. As the second surrounding portion 331 rotates forward about the second post 321, the second stopper hook 332 rotates upward and forward. When the second surrounding portion 331 rotates forward to its limit position, the second stopper hook 332 is precisely located within the second stopper 233.

[0144] As described above, the second limiting hook 332 has a simple structure and cooperates with the second surrounding portion 331 ingeniously to stably and reliably limit the forward rotation angle of the second surrounding portion 331 .

[0145] Please see the attached Figure 6 In certain embodiments of the present application, the first post 231 and the second post 321 are arranged side by side along the width of the cowl door assembly. The first and second stoppers 232, 233 are both formed on the first male hinge 23 and extend downward. The first and second stoppers 232, 233 correspond to the first and second stopper hooks 242, 332, respectively.

[0146] It should be noted that, along the Z direction, the first limiting portion 232 is located above the first column 231 , and the second limiting portion 233 is located above the second column 321 .

[0147] The first limiting portion 232 and the second limiting portion 233 are both arranged on the first male hinge 23 . They are arranged compactly and centrally, making their processing and manufacturing more convenient and faster, saving time and effort.

[0148] Please see the attached Figure 6 In some embodiments of the present application, the lowest height of the second limiting portion 233 extending downward is greater than the lowest height of the first limiting portion 232 extending downward.

[0149] It should be noted that when the first limiting portion 232 and the second limiting portion 233 extend downward from the same height, the downward extension length of the second limiting portion 233 is less than the downward extension length of the first limiting portion 232. The extension lengths of the first limiting hook 242 and the second limiting hook 332 are not specifically limited, as long as the first limiting hook 242 can be in contact with the first limiting portion 232 and the second limiting hook 332 can be in contact with the second limiting portion 233.

[0150] As described above, it can be ensured that the maximum forward rotation angle of the second surrounding portion 331 connected to the second limiting hook 332 is greater than the maximum forward rotation angle of the first surrounding portion 241 connected to the first limiting hook 242, so the maximum opening and flipping angle of the lower flip door 31 is greater than the maximum opening and flipping angle of the upper flip door 21.

[0151] When the upper flip door 21 and the lower flip door 31 are fixed as a whole and opened and flipped synchronously relative to the vehicle body frame 11, the first surrounding portion 241 and the second surrounding portion 331 rotate synchronously at the same angle, thereby driving the first limiting hook 242 and the second limiting hook 332 to rotate synchronously at the same angle; when the first surrounding portion 241 rotates forward to the extreme position, the first limiting hook 242 is limited by the first limiting portion 232, so that the upper flip door 21 is opened and flipped to the extreme angle; at this time, the second limiting hook 332 is not in a state of being limited by the second limiting portion 233, and the second surrounding portion 331 can still rotate forward, thereby realizing the opening and flipping of the lower flip door 31 relative to the upper flip door 21.

[0152] Please see the attached Figure 5-6 In certain embodiments of the present application, the first male hinge 23 includes a first mounting plate 234 and a first receiving plate 235 that are vertically connected; the first mounting plate 234 is perpendicular to the Z direction, and the first receiving plate 235 is perpendicular to the Y direction. The first column 231 is vertically fixed to the first receiving plate 235. The first limiting portion 232 and the second limiting portion 233 are both vertically arranged on the bottom surface of the first mounting plate 234, or the first limiting portion 232 and the second limiting portion 233 are both vertically arranged on the side of the first receiving plate 235 that fixes the first column 231; the first limiting portion 232 and the second limiting portion 233 are both perpendicular to the X direction, and the two are arranged side by side along the Y direction. Furthermore, the first mounting plate 234 and the first supporting plate 235 are an integrally connected L-shaped structure; the first limiting portion 232 and the second limiting portion 233 are an integrally connected structure, and the downward extension length of the second limiting portion 233 relative to the first mounting plate 234 is smaller than the downward extension length of the first limiting portion 232 relative to the first mounting plate 234.

[0153] Please see the attached Figure 5-6 11. Furthermore, the first female hinge 24 includes a second mounting plate 243 and a second receiving plate 244, which are vertically connected. The second mounting plate 243 is perpendicular to the X-axis, and the second receiving plate 244 is perpendicular to the Y-axis. The first surrounding portion 241 is a first U-shaped groove formed in the second receiving plate 244, with the opening of the first U-shaped groove being the first notch. Furthermore, the second mounting plate 243 and the second receiving plate 244 form an integrally connected L-shaped structure; the first limiting hook 242 and the second receiving plate 244 are integrally connected.

[0154] Please see the attached Figure 5-6 In some embodiments, the second male hinge 32 includes an integrally connected third mounting plate 322 and a third receiving plate 323 . The third mounting plate 322 and the third receiving plate 323 are integrally connected vertically and perpendicular to the Y-axis. The second column 321 is vertically fixed to the third receiving plate 323 .

[0155] Please see the attached Figure 5-613. Furthermore, the second female hinge 33 includes a fourth mounting plate 333 and a fourth receiving plate 334, which are vertically connected. The fourth mounting plate 333 is perpendicular to the X-axis, and the fourth receiving plate 334 is perpendicular to the Y-axis. The second surrounding portion 331 is a second U-shaped groove formed in the fourth receiving plate 334, with the opening of the second U-shaped groove being the second notch. Furthermore, the fourth mounting plate 333 and the fourth receiving plate 334 form an integrally connected L-shaped structure.

[0156] Please see the attached Figure 4 In certain embodiments of the present application, the cowl door device includes a mounting base 4 , which is fixed to the vehicle body frame 11 and is used to fix the first male hinge 23 .

[0157] As mentioned above, the mounting seat 4 provides an installation point for the first male hinge 23 to be installed and fixed on the vehicle body frame 11, and the position of the first male hinge 23 can be adjusted to achieve accurate and reliable articulated assembly of the first male hinge 23 and the first female hinge 24.

[0158] Please see the attached Figure 4 In some embodiments, the cowl door device includes a first locking assembly 5 to achieve locking or unlocking of the flip door 21 and the vehicle body frame 11 .

[0159] Furthermore, the first locking assembly 5 includes a first locking bumper 51 mounted on the vehicle body frame 11 and a first locking mechanism 52 mounted on the flip door 21. When the flip door 21 is overlaid on the vehicle body frame 11, the first locking mechanism 52 is locked to the first locking bumper 51, thereby locking the flip door 21 to the vehicle body frame 11. When the first locking mechanism 52 is triggered, the first locking mechanism 52 is released from the first locking bumper 51, thereby completing the opening and flipping of the flip door 21.

[0160] Furthermore, the first locking mechanism 52 triggers the unlocking of the first lock bumper 51 through the pull-wire opening mechanism 9. The pull-wire opening mechanism 9 includes an opening handle 91 and an opening pull wire 92. The opening handle 91 is arranged at the bottom of the upper door frame 22, so that a person can reach into the lower door 31 from the bottom and operate the opening handle 91. The opening pull wire 92 is connected to the first locking mechanism 52 at one end and to the opening handle 91 at the other end. When the opening handle 91 is operated, the opening pull wire 92 is actuated, and the first locking mechanism 52 is actuated through the opening pull wire 92, thereby releasing the first locking mechanism 52 from the first lock bumper 51.

[0161] It should be further explained that, in other embodiments, the first locking assembly 5 may be an existing electromagnetic locking mechanism, that is, the locking of the flip door 21 is controlled by an electric switch.

[0162] Please see the attached Figure 4In some embodiments, the cowl door device includes a second locking assembly 6 to achieve locking or unlocking of the lower flip door 31 and the upper flip door 21 .

[0163] Furthermore, the second locking assembly 6 includes a second lock stopper 61 mounted on the lower door 31 and a second locking mechanism 62 mounted on the upper door frame 22. When the lower door 31 is overlaid on the upper door frame 22, the second locking mechanism 62 is locked to the second lock stopper 61, thereby locking the lower door 31 to the upper door 21. When the second locking mechanism 62 is triggered, the second locking mechanism 62 is released from the second lock stopper 61, thereby completing the opening and flipping of the lower door 31.

[0164] Furthermore, the second locking machine 62 is a card plate locking machine, and the second locking machine 62 can be released from the second lock bump 61 by manually moving the clamping part of the second locking machine 62.

[0165] It should be further explained that, in other embodiments, the second locking assembly 6 may be an existing electromagnetic locking mechanism, that is, the locking of the lower flip door 31 is controlled by an electric switch.

[0166] Please see the attached Figure 4 In certain embodiments of the present application, the front door device includes a limiting pull rope 7 that can be fixed to the vehicle body frame 11 to fix the flip angle of the upper flip door 21 and / or to fix the flip angle of the lower flip door 31.

[0167] It should be noted that one end of the retaining cord 7 can be fastened to a first retaining hole provided on the vehicle body frame 11, and the other end can be fastened to a second retaining hole provided on the flip door 21. By binding the retaining cord 7 between the vehicle body frame 11 and the flip door 21, the flip door 21's opening angle is fixed. The flip door 21's opening angle can be varied by changing the length of the retaining cord 7 between the first and second retaining holes. The flip door 21 can only be removed from the vehicle body frame 11 by releasing the ties securing the retaining cord 7 in the first and / or second retaining holes.

[0168] It should be further explained that one end of the limiter cord 7 can be fastened to a third limiter hole provided on the vehicle body frame 11, and the other end can be fastened to a fourth limiter hole provided on the lower flap 31. By binding the limiter cord 7 between the vehicle body frame 11 and the lower flap 31, the opening angle of the lower flap 31 is limited. The opening angle of the lower flap 31 can be varied by changing the length of the limiter cord 7 between the third and fourth limiter holes. The lower flap 31 can only be disassembled and freed from the upper flap frame 22 by releasing the ties securing the limiter cord 7 to the third and / or fourth limiter holes.

[0169] It should be noted that the first and third limiting holes can be two independent limiting holes provided on the vehicle body frame 11, or they can be a single limiting hole provided on the vehicle body frame 11. Only one limiting pull cord 7 can be provided to select a fixed opening and tilting angle for the upper and lower doors 21 and 31 in a specific scenario. Of course, multiple limiting pull cords 7 can also be provided to independently fix the opening and tilting angles of the upper and lower doors 21 and 31.

[0170] Please see the attached Figure 4 In certain embodiments of the present application, a limiting elastic member 8 is formed on a side surface of the flip door 21 close to the vehicle body frame 11 .

[0171] It should be noted that multiple position-limiting elastic members 8 are provided, distributed on both sides of the flip door 21 along the Y direction. The area between the vehicle frame 11 and the position-limiting elastic members 8 constitutes the vehicle frame buffer zone. Furthermore, a buffer member that cooperates with the position-limiting elastic members 8 can be provided in the vehicle frame buffer zone. The position-limiting elastic members 8 can be selected from door body position-limiting bolts.

[0172] By setting the limiting elastic member 8, the anti-collision buffering can be ensured when the upper flip door 21 is closed and flipped to cover the vehicle body frame 11; at the same time, the stability of the locking and fixing of the first lock bumper 51 and the first lock machine 52 can also be ensured.

[0173] Please see the attached Figure 6 、 14 In certain embodiments of the present application, the mounting base 4 includes a fifth mounting plate 41. One of the first mounting plate 234 of the first male hinge 23 and the fifth mounting plate 41 of the mounting base 4 is provided with a first X-direction strip hole, and the other is provided with a first Y-direction strip hole a. A first fastener is passed through the first X-direction strip hole and the first Y-direction strip hole a, respectively, to securely connect the first mounting plate 234 to the fifth mounting plate 41, thereby securing the first male hinge 23 to the mounting base 4.

[0174] It should be noted that the X-direction is parallel to the vehicle's front-to-back direction; the direction in which the X-direction strip-shaped holes extend is parallel to the vehicle's front-to-back direction. The Y-direction is parallel to the vehicle's width direction; the direction in which the Y-direction strip-shaped holes extend is parallel to the vehicle's width direction. The Z-direction is parallel to the vehicle's height direction; the direction in which the Z-direction strip-shaped holes extend is parallel to the vehicle's height direction.

[0175] Furthermore, the mounting base 4 is a rectangular parallelepiped frame structure, and the bottom side panels of the mounting base 4 serve as the fifth mounting plate 41. The first mounting plate 234 of the first male hinge 23 is mounted on the bottom of the fifth mounting plate 41. Preferably, along the X-axis, the front and rear side panels of the rectangular frame are both missing, forming front and rear openings, thereby providing operating space for the installation and fixation of the first fastener.

[0176] Preferably, the first mounting plate 234 of the first male hinge 23 defines a first Y-axis strip hole a, and the fifth mounting plate 41 of the mounting base 4 defines a first X-axis strip hole. Multiple sets of the first Y-axis strip holes a and the first X-axis strip holes are provided, one-to-one matching; preferably, three sets are provided, arranged in a triangular pattern. The first fastener can be a fastening bolt or a fastening pin; preferably, the first fastener is a fastening bolt.

[0177] By cross-coordinating the first X-direction strip hole and the first Y-direction strip hole a, the position of the first mounting plate 234 relative to the fifth mounting plate 41 in the X-direction and Y-direction can be adjusted, thereby ensuring the accuracy and reliability of the hinged assembly of the first male hinge 23 and the first female hinge 24 in the X-direction and Y-direction.

[0178] Please see the attached Figure 15 In some embodiments, one of the flip door frame 22 and the first female hinge 24 defines a first mounting hole, and the other defines a first Z-axis strip hole b. A second fastener is passed through the first mounting hole and the first Z-axis strip hole b, respectively, to securely connect the flip door frame 22 to the second mounting plate 243.

[0179] It should be noted that the upper door frame 22 includes a first plate 221, and the first plate 221 is perpendicular to the X-axis. Preferably, the first plate 221 of the upper door frame 22 is provided with a first mounting hole, and the second mounting plate 243 of the first female hinge 24 is provided with a first Z-axis strip hole b. The first mounting hole can be a strip hole in any direction that is cross-assembled with the first Z-axis strip hole b, or it can be a circular hole; preferably, the first mounting hole is a circular hole. The first mounting holes and the first Z-axis strip holes b are provided in multiple groups in a one-to-one matching manner; preferably, three groups are provided and arranged in a triangular shape. The second fastener can be a fastening bolt or a fastening pin; preferably, the second fastener is a fastening bolt.

[0180] By cooperating with the first mounting hole and the first Z-direction strip hole b, the position of the second mounting plate 243 relative to the first plate 221 in the Z direction can be adjusted, thereby ensuring the accuracy and reliability of the hinged assembly of the first female hinge 24 and the first male hinge 23 in the Y direction.

[0181] Please see the attached Figure 16 In some embodiments, the first locking bumper 51 of the first locking assembly 5 includes a sixth mounting plate 511. A third X-axis strip hole is defined in one of the vehicle body frame 11 and the sixth mounting plate 511, and a third Z-axis strip hole e is defined in the other. A fifth fastener is inserted through the third X-axis strip hole and the third Z-axis strip hole e, respectively, to securely connect the vehicle body frame 11 to the sixth mounting plate 511.

[0182] Preferably, the vehicle body frame 11 is provided with a third X-axis strip hole, and the sixth mounting plate 511 of the first locking bumper 51 is provided with a third Z-axis strip hole e. Multiple sets of third X-axis strip holes and third Z-axis strip holes e are provided in a one-to-one matching pattern; preferably, three sets are provided, arranged in a triangular pattern. The fifth fastener can be a fastening bolt or a fastening pin; preferably, the fifth fastener is a fastening bolt.

[0183] Through the cross-matching of the third X-direction strip hole and the third Z-direction strip hole e, the position adjustment of the first lock bumper 51 relative to the vehicle body frame 11 in the X-direction and Z-direction can be achieved, thereby ensuring the precise reliability of the locking match between the first lock bumper 51 and the first lock machine 52 in the X-direction and Z-direction.

[0184] As can be seen from the above, the first male hinge 23 and the first female hinge 24 have sufficient adjustment space in the three directions of X, Y and Z, so that the first male hinge 23 and the first female hinge 24 can be accurately and reliably hinged and assembled together; at the same time, because the first lock bump 51 and the first lock mechanism 52 are free to cooperate in the Y direction, the first lock bump 51 and the first lock mechanism 52 have sufficient adjustment space in the three directions of X, Y and Z; as above, it becomes very easy to ensure the adjustment of the gap surface difference of the upper flip door 21 relative to the vehicle body frame 11.

[0185] Please see the attached Figure 17 In some embodiments, one of the flip door frame 22 and the third mounting plate 322 of the second male hinge 32 has a second X-axis strip hole, and the other has a second Z-axis strip hole c. A third fastener is passed through the second X-axis strip hole and the second Z-axis strip hole c, respectively, to securely connect the flip door frame 22 to the third mounting plate 322.

[0186] It should be noted that the flip-up door frame 22 includes a second plate 222 perpendicularly connected to the first plate 221, with the second plate 222 perpendicular to the Y-axis. Preferably, the second plate 222 of the flip-up door frame 22 is provided with a second X-axis strip hole, and the third mounting plate 322 of the second male hinge 32 is provided with a second Z-axis strip hole c.
