Description

Technical Field

[0001] This invention relates to the field of automotive technology, and more particularly to a flip-up door hinge mechanism and an automobile. Background Technology

[0002] Existing automotive tilt-and-turn doors typically connect to the vehicle body via a hinge mechanism to open and close. In related technologies, the hinges between the tilt-and-turn door and the vehicle body often use fasteners to fix both ends of the hinge to the door and the vehicle body respectively. When the door needs to be disassembled for repair, replacement, or assembly, tools are usually required to remove each fastener individually, making the door disassembly and assembly process cumbersome and hindering rapid disassembly. Furthermore, to meet the load-bearing requirements of tilt-and-turn doors, existing hinge mechanisms are usually quite heavy, which is detrimental to the overall lightweight design of the vehicle.

[0003] Therefore, there is an urgent need for a flip-door hinge mechanism and an automobile to solve the above problems. Summary of the Invention

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0021] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0023] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0024] Example 1 This embodiment provides a flip-door hinge mechanism, such as Figures 1-3 As shown, the flip-top door hinge mechanism includes a door frame 100 and a door body 200. The door frame 100 has an opening 101, and the upper edge of the opening 101 has a first mounting opening 1111. The top of the door body 200 has a hinge portion 210, which is inserted into the first mounting opening 1111. The hinge portion 210 includes multiple sliding segments connected in sequence, with an included angle between adjacent sliding segments. Each sliding segment is slidably engaged with the first mounting opening 1111. The door body 200 can rotate sequentially around the connection position between adjacent sliding segments. The door body 200 has an open position, a closed position, and a disassembly position between the open and closed positions. When the door body 200 rotates to the disassembly position, the hinge portion 210 can disengage from the first mounting opening 1111, thereby realizing the quick disassembly and assembly of the door body 200, improving the efficiency of door body 200 maintenance, replacement, and assembly, while also simplifying the structure of the flip-top door hinge mechanism and reducing the overall vehicle weight.

[0025] like Figures 2-3As shown, the hinge portion 210 includes a first sliding segment 211, a second sliding segment 212, a third sliding segment 213, and a fourth sliding segment 214 connected in sequence. The first sliding segment 211, the second sliding segment 212, and the third sliding segment 213 bend sequentially toward one side of the door body 200, and the fourth sliding segment 214 bends toward the other side of the door body 200. The fourth sliding segment 214 is configured to prevent the hinge portion 210 from disengaging from the first mounting opening 1111 when the door body 200 is in the open position, and to disengage from the first mounting opening 1111 when the door body 200 is in the disassembled position. During the flipping process of the door body 200, the first sliding segment 211, the second sliding segment 212, the third sliding segment 213, and the fourth sliding segment 214 slide and engage sequentially with the first mounting opening 1111. After each slide, the door body 200 can flip using the connection point between two adjacent sliding segments as a pivot point, thereby achieving a flipping and opening function similar to a hinge. Furthermore, since the bending direction of the fourth sliding segment 214 is opposite to that of the third sliding segment 213, the fourth sliding segment 214 of the hinge part 210 can only disengage from the first assembly port 1111 along the corresponding trajectory when the door body 200 is rotated to the disassembly position. It is difficult to disengage when the door body 200 is opened at too large or too small an angle, thereby ensuring the stable connection of the door body 200 while realizing the rapid disassembly of the door body 200.

[0026] like Figure 1 As shown, two hinge portions 210 are provided at the top of the door body 200, and two first mounting openings 1111 are provided along the upper edge of the door frame 100. The hinge portions 210 are inserted into the first mounting openings 1111 in a one-to-one correspondence, which can improve the stability of the door body 200 during opening and closing. Optionally, the first mounting opening 1111 is a rectangular opening extending along the width direction of the vehicle body, and the first sliding section 211, the second sliding section 212, the third sliding section 213, and the fourth sliding section 214 of the hinge portion 210 are all plate-shaped.

[0027] like Figure 3 and Figure 4 As shown, the upper edge of the opening 101 is provided with a first U-shaped portion 110, which is formed by a first plate 111, a second plate 112 and a third plate 113. The second plate 112 is provided with a first mounting opening 1111, which facilitates the insertion of the hinge portion 210 into the first mounting opening 1111 of the door frame 100, thereby improving the ease of assembly and disassembly. Furthermore, the first U-shaped portion 110 is formed by the first plate 111, the second plate 112 and the third plate 113, which helps to improve the structural strength and connection stability of the connection between the door frame 100 and the hinge portion 210, and prevents the door frame 100 from deforming during the flipping of the door body 200.

[0028] like Figure 5As shown, the door frame 100 is also provided with a second U-shaped portion 120, a third U-shaped portion 130 and a fourth U-shaped portion 140. The first U-shaped portion 110, the second U-shaped portion 120, the third U-shaped portion 130 and the fourth U-shaped portion 140 are arranged sequentially along the circumference of the opening 101, so that the door body 200 can be recessed into the door frame 100 when closed, thereby reducing the degree of protrusion of the door body 200 relative to the door frame 100 and improving the overall flatness and appearance of the door frame 100 after the door body 200 is connected.

[0029] Optionally, the flip-up door hinge mechanism also includes a first seal, which is disposed between the first sliding section 211 and the first plate 111. By providing the first seal, the gap between the top of the door body 200 and the upper edge of the door frame 100 can be sealed when the door body 200 is in the closed position, preventing dust, moisture, etc. from entering the vehicle body and improving the user experience.

[0030] Optionally, the door body 200 is provided with a recess 220, and a second sealing element is provided between the top of the recess 220 and the third plate 113, which can further improve the sealing performance between the door body 200 and the door frame 100.

[0031] Optionally, the first and second seals can be rubber or silicone parts, which have a certain deformation capacity to ensure the reliability of the seal.

[0032] Optionally, the first plate 111 is provided with multiple second assembly ports, and the top of the door body 200 is provided with multiple tenons, which are inserted into the second assembly ports one by one. By setting the tenons to be inserted into the second assembly ports, the relative position between the door body 200 and the door frame 100 can be positioned, which helps to control the assembly surface difference between the door body 200 and the door frame 100, and improves the positional accuracy and assembly consistency of the door body 200 when it is in the closed position.

[0033] In this embodiment, five tenons are provided at the upper end of the door body 200, and correspondingly, five second mounting openings are provided on the first plate 111. The tenons and the second mounting openings are inserted one-to-one to ensure that the surface difference of the door body 200 in the closed position meets the design requirements and improves the overall appearance quality of the vehicle. In other embodiments, two, three, four, or six tenons can be provided on the door body 200, and the number of tenons is not specifically limited.

[0034] like Figure 5As shown, the bottom end of the door frame 100 is provided with a support groove 150. The support groove 150 is configured to support the door body 200 when the door body 200 is in the closed position. It can support the door body 200 during the assembly process and play a preliminary positioning role for the door body 200. This helps to improve the assembly efficiency and accuracy of the door body 200, while reducing the risk of the door body 200 falling and improving the safety of use.

[0035] Optionally, the bottom of the door body 200 is fixed to the door frame 100 by fasteners, which can ensure the firmness of the connection between the door body 200 and the door frame 100 during driving and prevent the door body 200 from opening accidentally due to vibration or inertia.

[0036] In one embodiment, the bottom end of the door 200 is fixed to the door frame 100 by a lock 300, which also secures the door 200 to the door frame 100, ensuring driving safety and preventing the door 200 from being opened accidentally. It should be noted that the lock 300 can be any lock structure in the prior art, and the specific structure of the lock 300 will not be described in detail.

[0037] In another embodiment, a clamping member is provided on the door frame 100, which is configured to press the door body 200 against the door frame 100, thereby improving the firmness and stability of the connection between the door body 200 and the door frame 100, and reducing the possibility of the door body 200 being opened accidentally.

[0038] Furthermore, the clamping component can be another door body 200, that is, two door bodies 200 arranged vertically are provided on the same door frame 100, and the upper edge of the lower door body 200 is configured to press against the lower edge of the upper door body 200, thereby achieving the clamping and fixing of the upper door body 200, thus achieving the ultimate lightweight design.

[0039] Optionally, the bottom of the door 200 is also provided with a handle 160, which provides a position for the user to apply force, making it easier to open and close the door 200 and improving the convenience of operation.

[0040] The operation process of the flip-door hinge mechanism provided in this embodiment is roughly as follows: First, such as Figure 1 As shown, when the door 200 is in the closed position, the door 200 is fixed to the door frame 100 by the lock 300 and / or fasteners to improve the stability of the connection between the door 200 and the door frame 100.

[0041] When it is necessary to open the door 200, unlock the lock 300 and / or remove the fasteners, such as Figures 3-6As shown, the user applies force through the handheld part 160 to flip the door 200 upward. The door 200 first rotates around the connection point between the first sliding section 211 and the second sliding section 212 as the pivot point. Then, the user pulls the door 200 downward, causing the second sliding section 212 to slide relative to the first mounting opening 1111. The door 200 then continues to flip upward around the connection point between the second sliding section 212 and the third sliding section 213 as the pivot point. After flipping to a certain extent, the user continues to pull the door 200 along the extension direction of the third sliding section 213, causing the third sliding section 213 to slide along the first mounting opening 1111. Then, the door 200 rotates around the connection point between the third sliding section 213 and the fourth sliding section 214 as the pivot point until it flips to the open position. At this time, since the bending direction of the fourth sliding section 214 is opposite to that of the third sliding section 213, the hinge part 210 cannot disengage from the first mounting opening 1111 due to the restriction of the fourth sliding section 214, thus improving the safety of the door 200 in the open position. The process of closing door 200 is the reverse of the process of opening door 200, and will not be described in detail.

[0042] like Figure 7 and Figure 8 As shown, when it is necessary to disassemble the door body 200, first close the door body 200 downwards to the disassembly position, so that the extension direction of the fourth sliding section 214 is roughly aligned with the orientation of the first assembly port 1111. Then, by rotating and pulling the door body 200, the fourth sliding section 214 can be taken out from the first assembly port 1111, thereby realizing the quick disassembly and assembly of the door body 200.

[0043] Example 2 like Figures 9-11 As shown, this embodiment provides a flip-top door hinge mechanism, which is basically the same as that of Embodiment 1, except that the hinge portion 210 includes a fifth sliding segment 215, a C-shaped sliding segment 216, and a sixth sliding segment 217 connected in sequence. The C-shaped sliding segment 216 slides with the first mounting opening 1111. During the opening of the door 200, the first C-shaped sliding segment 216 of the door 200 rotates as a fulcrum. The sixth sliding segment 217 is configured to restrict the hinge portion 210 from disengaging from the first mounting opening 1111 when the door 200 is in the open position, and to allow the hinge portion 210 to disengage from the first mounting opening 1111 when the door 200 is in the disassembled position. This enables quick disassembly and assembly of the door 200, improves the efficiency of door maintenance, replacement, and assembly, and simplifies the structure of the flip-top door hinge mechanism while reducing the overall vehicle weight. In this embodiment, the flip-top door hinge mechanism is simpler and easier to manufacture, reducing manufacturing difficulty and production costs.

[0044] Optionally, one end of the fifth sliding segment 215 is connected to one end of the C-shaped sliding segment 216, and the other end is connected to the door body 200. The sidewalls of the fifth sliding segment 215 and the C-shaped sliding segment 216 are parallel. A sixth sliding segment 217 is provided at the end of the C-shaped sliding segment 216 away from the fifth sliding segment 215, and the sixth sliding segment 217 is perpendicular to the sidewall of the C-shaped sliding segment 216. By forming a turning structure between the sixth sliding segment 217 and the C-shaped sliding segment 216, the hinge 210 is difficult to detach along the extension direction of the first assembly opening 1111 when the door body 200 is in the open position. This helps to improve the connection stability of the door body 200 in the open state and reduces the possibility of the door body 200 accidentally falling off. Furthermore, when the door body 200 is rotated to the disassembly position, the relative positional relationship between the sixth sliding segment 217 and the first assembly opening 1111 changes, allowing the hinge 210 to detach from the first assembly opening 1111 along a preset trajectory, thereby realizing the quick assembly and disassembly of the door body 200.

[0045] It should be noted that the C-shaped sliding section 216 between the fifth sliding section 215 and the sixth sliding section 217 can be understood as the connection position between two adjacent sliding sections. When the door 200 flips, it can rotate with the C-shaped sliding section 216 as the fulcrum.

[0046] The operation process of the flip-door hinge mechanism provided in this embodiment is roughly as follows: First, when the door 200 is in the closed position, the door 200 is fixed to the door frame 100 by the lock 300 and / or fasteners to improve the stability of the connection between the door 200 and the door frame 100.

[0047] When it is necessary to open the door 200, unlock the lock 300 and / or remove the fasteners, such as Figures 9-10 As shown, the user applies force through the handheld part 160 to flip the door 200 upwards. The door 200 flips using the bend of the C-shaped sliding section 216 as a pivot point. During the flipping process, the C-shaped sliding section 216 slides relative to the first mounting opening 1111 until the door 200 reaches the open position. At this time, the sixth sliding section 217 prevents the hinge part 210 from disengaging along the first mounting opening 1111, thereby improving the connection stability of the door 200 in the open position.

[0048] When it is necessary to close the door 200, the door 200 moves along the opposite path to the opening process, which will not be described in detail here.

[0049] like Figure 11 As shown, when it is necessary to disassemble the door body 200, the door body 200 is first rotated to the disassembly position so that the relative position of the sixth sliding section 217 and the first assembly port 1111 meets the disassembly condition. Then, by rotating and pulling, the sixth sliding section 217 is disassembled from the first assembly port 1111, thereby realizing the quick disassembly of the door body 200.

[0050] Example 3 This embodiment provides an automobile, including a vehicle body and a flip-up door hinge mechanism as described in any of the above embodiments. By employing the flip-up door hinge mechanism, the automobile door 200 can be flipped open and quickly disassembled, thereby improving the efficiency of door 200 maintenance, replacement, and assembly; furthermore, it helps to simplify the connection structure of the door 200 and reduce the overall vehicle weight.

[0051] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
