Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, specifically to a hinge mechanism, a handrail box, and a vehicle. Background Technology

[0002] Car armrests typically require metal hinges, but the different sizes of different car models result in variations in the size of the armrests. This means that different projects need to develop armrest metal hinges of different sizes, which increases both mold development costs and development time, leading to a significant waste of both costs and time. Utility Model Content

[0003] This utility model provides a hinge mechanism, an armrest box, and a vehicle, wherein the size of the hinge mechanism is adjustable to adapt to the armrest box specifications of different vehicle models.

[0004] In a first aspect, this utility model provides a hinge mechanism, the hinge mechanism comprising:

[0005] Upper mounting bracket assembly, the upper mounting bracket assembly comprising:

[0006] First upper frame component;

[0007] A second upper frame assembly is connected to the first upper frame assembly, and the first and second upper frame assemblies have multiple mating connection positions to allow the dimensions of the upper mounting frame assembly to be adjustable in the relative directions of the first and second upper frame assemblies; and

[0008] Lower mounting bracket assembly, the lower mounting bracket assembly comprising:

[0009] The first lower frame assembly is rotatably connected to the first upper frame assembly;

[0010] The second lower frame assembly is rotatably connected to the second upper frame assembly and connected to the first lower frame assembly. The first lower frame assembly and the second lower frame assembly have multiple mating connection positions so that the dimensions of the lower mounting frame assembly are adjustable in the relative directions of the first lower frame assembly and the second lower frame assembly.

[0011] The first upper frame assembly and the second upper frame assembly are snap-fitted together, and the first upper frame assembly and the second upper frame assembly have multiple snap-fitting positions, so that the size of the upper mounting frame assembly in the relative direction of the first upper frame assembly and the second upper frame assembly is adjustable.

[0012] The first upper frame assembly includes a first upper connector, and the second upper frame assembly includes a second upper connector. The first upper connector is provided with a plurality of first card interfaces, which are arranged at intervals along the relative directions of the first upper frame assembly and the second upper frame assembly. The second upper connector is provided with a first card connector, which is snapped into any one of the first card interfaces.

[0013] The first upper connector has a receiving space that is connected to the first card interface. The second upper connector includes a main body and a plug-in part that are connected to each other. The plug-in part has a first card connector and is inserted into the receiving space so that the first card connector is engaged with the first card interface.

[0014] The insertion part includes an insertion body and a deformation part. Both opposite ends of the deformation part are connected to the insertion body to form a deformation space together with the insertion body. The first snap-fit ​​connector protrudes from the side of the deformation part away from the deformation space.

[0015] The first upper frame assembly includes a first upper bracket and a first upper extension member. The first upper bracket is directly or indirectly connected to the second upper frame assembly, the first upper extension member is rotatably connected to the first lower frame assembly, the first upper bracket is connected to the first upper extension member, and the first upper bracket and the first upper extension member have multiple mating connection positions so that the first upper bracket can be close to or away from the first lower frame assembly.

[0016] The second upper frame assembly includes a second upper bracket and a second upper extension member. The second upper bracket is directly or indirectly connected to the first upper frame assembly, the second upper extension member is rotatably connected to the second lower frame assembly, the second upper bracket is connected to the second upper extension member, and the second upper bracket and the second upper extension member have multiple mating connection positions so that the second upper bracket can be close to or away from the second lower frame assembly.

[0017] The first upper support includes a first support portion and a second support portion that are bent and connected together. The first support portion is directly or indirectly connected to the second upper frame assembly, and the second support portion is connected to the first upper extension piece.

[0018] The second bracket portion is provided with a plurality of first mounting holes, each of which is at a different distance from the first bracket portion. The first upper extension is provided with a plurality of second mounting holes, the arrangement direction of which is the same as that of which is the arrangement direction of which is the first mounting holes, and at least one pair of first mounting holes and second mounting holes are arranged opposite to each other to allow fasteners to pass through.

[0019] The first upper support includes a first support portion and a second support portion that are bent and connected together. The first support portion is directly or indirectly connected to the second upper frame assembly, and the second support portion is connected to the first upper extension piece.

[0020] The second bracket is provided with a plurality of first mounting holes, and the distance from each first mounting hole to the first bracket is different. The first upper extension is provided with a second mounting hole, which is arranged opposite to any one of the first mounting holes to allow fasteners to pass through.

[0021] Alternatively, the second bracket portion may have a first mounting hole, and the first upper extension may have multiple second mounting holes. The distance from each second mounting hole to the first bracket portion may be different. The first mounting hole may be positioned opposite to any one of the second mounting holes to allow fasteners to pass through.

[0022] Secondly, this utility model provides an armrest box, which includes a box body, a cover body, and a hinge mechanism.

[0023] Thirdly, this utility model provides a vehicle, which includes a body assembly and an armrest box, the body assembly having an interior space, and the armrest box being disposed within the interior space.

[0024] In the hinge mechanism provided by this utility model, since the first upper frame assembly and the second upper frame assembly have multiple mating connection positions, during the assembly stage, the upper mounting bracket assembly can select the mating connection position according to the required width dimension (i.e., the dimension in the relative direction of the first upper frame assembly and the second upper frame assembly, i.e., the dimension in the X-axis direction). Similarly, since the first lower frame assembly and the second lower frame assembly also have multiple mating connection positions, during the assembly stage, the lower mounting bracket assembly can select the mating connection position according to the required width dimension (i.e., the dimension in the relative direction of the first lower frame assembly and the second lower frame assembly, i.e., the dimension in the X-axis direction). It can be understood that the selectability of the width dimension in the X-axis direction for both the upper and lower mounting bracket assemblies means that the overall width of the hinge mechanism in the X-axis direction is adjustable. That is, the overall width of the hinge mechanism can be flexibly and quickly adjusted according to different vehicle models, enabling different vehicle models to share a single hinge mechanism, thereby saving development costs and shortening the cycle.

Detailed Implementation

[0051] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0052] In this document, references to "embodiment" or "implementation" mean that a particular feature, structure, or characteristic described in connection with an embodiment or implementation may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0053] Please refer to Figure 1This utility model also provides a vehicle 1, which may be, but is not limited to, a sedan, station wagon, MPV, SUV, sports car, pickup truck, van, bus, etc. The vehicle 1 includes a body assembly 2 and an armrest box 3. The body assembly 2 has an interior space X1, and the armrest box 3 is disposed within the interior space X1.

[0054] Please refer to Figure 2 and Figure 3 The present invention also provides an armrest box 3, which includes a box body 4, a cover 5, and a hinge mechanism 6 as described in any embodiment of the present invention. The cover 5 is connected to the upper mounting bracket assembly 10 of the hinge mechanism 6, and the box body 4 is connected to the lower mounting bracket assembly 20 of the hinge mechanism 6, so that the cover 5 can rotate relative to the box body 4.

[0055] The storage compartment 4 has a storage space for placing items. A lid 5, which can be rotated open and closed, covers the storage space or supports the driver's elbow. The armrest box 3 has an open state (not shown) and a closed state (as shown). Figure 2 As shown, when the armrest box 3 is in the open state, the box body 4 and the cover 5 form a certain angle, and the storage space of the box body 4 is not blocked by the cover 5; when the armrest box 3 is in the closed state, the cover 5 closes to the box body 4, and the storage space of the box body 4 is blocked by the cover 5.

[0056] Please refer to Figure 3 This utility model provides a hinge mechanism 6, which can be adjusted in width and height to adapt to the specifications of armrest boxes 3 of different car models.

[0057] It should be noted that the so-called adjustable width (or height) in this utility model means that, during the assembly stage of the hinge mechanism 6, hinge mechanisms 6 with different widths (or heights) can be assembled according to requirements. It does not imply that the width (or height) of the hinge mechanism 6 can still be adjusted after assembly. Whether the width (or height) of the hinge mechanism 6 can be adjusted after assembly is not limited here.

[0058] For ease of reading and understanding, the following content is divided into two parts to introduce the width adjustment and height adjustment of the hinge mechanism 6 respectively. Provided there are no obstacles to the connection, any implementation method in the two parts can be combined, and should not be regarded as the two parts being separate and unconnectable.

[0059] For ease of subsequent explanation, Figure 3The viewpoint shown defines an XYZ Cartesian coordinate system, where the X-axis is parallel to the width direction of hinge mechanism 6, the Y-axis is parallel to the height direction of hinge mechanism 6, and the Z-axis is parallel to the thickness direction of hinge mechanism 6. The direction pointed to by the arrows of the X / Y / Z axes is the positive direction of the X / Y / Z axes, and the opposite direction of the arrows of the X / Y / Z axes is the negative direction of the X / Y / Z axes. Please refer to this section for the following description of the coordinate system.

[0060] Part 1: Adjustable width of the hinge mechanism

[0061] Please refer to Figure 3 The hinge mechanism 6 includes an upper mounting bracket assembly 10 and a lower mounting bracket assembly 20. The upper mounting bracket assembly 10 is hinged to the lower mounting bracket assembly 20, meaning that the upper mounting bracket assembly 10 can rotate relative to the lower mounting bracket assembly 20.

[0062] Please refer to Figure 4 The upper mounting bracket assembly 10 includes a first upper bracket body assembly 110 and a second upper bracket body assembly 120. The second upper bracket body assembly 120 is connected to the first upper bracket body assembly 110. The first upper bracket body assembly 110 and the second upper bracket body assembly 120 have multiple mating connection positions, allowing the size of the upper mounting bracket assembly 10 in the relative direction (i.e., the X-axis direction) between the first upper bracket body assembly 110 and the second upper bracket body assembly 120 to be adjustable. That is, the first upper bracket body assembly 110 and the second upper bracket body assembly 120 have two or more mating connection positions. The first upper bracket body assembly 110 and the second upper bracket body assembly 120 are fixedly connected through any one of these mating connection positions. Furthermore, when the first upper bracket body assembly 110 and the second upper bracket body assembly 120 are fixedly connected through different mating connection positions, the corresponding size of the upper mounting bracket assembly 10 in the X-axis direction is different. Therefore, during the assembly stage, the appropriate mating connection position can be selected based on the determined size of the upper mounting bracket assembly 10 in the X-axis direction.

[0063] Please refer to Figure 4The lower mounting bracket assembly 20 includes a first lower bracket body assembly 210 and a second lower bracket body assembly 220. The first lower bracket body assembly 210 is hinged to the first upper bracket body assembly 110. The second lower bracket body assembly 220 is hinged to the second upper bracket body assembly 120. The second lower bracket body assembly 220 is connected to the first lower bracket body assembly 210. The first lower bracket body assembly 210 and the second lower bracket body assembly 220 have multiple mating connection positions, allowing the size of the lower mounting bracket assembly 20 to be adjustable in the relative direction (i.e., the X-axis direction) between the first lower bracket body assembly 210 and the second lower bracket body assembly 220. In other words, the first lower frame assembly 210 and the second lower frame assembly 220 have two or more mating connection points. The first lower frame assembly 210 and the second lower frame assembly 220 are fixedly connected through any one of these mating connection points. Furthermore, when the first lower frame assembly 210 and the second lower frame assembly 220 are fixedly connected through different mating connection points, the corresponding dimensions of the lower mounting frame assembly 20 in the X-axis direction are different. Therefore, during the assembly stage, the appropriate mating connection point can be selected based on the dimensions of the lower mounting frame assembly 20 in the X-axis direction.

[0064] In summary, in the hinge mechanism 6 provided by this utility model, since the first upper frame assembly 110 and the second upper frame assembly 120 have multiple mating connection positions, during the assembly stage, the upper mounting bracket assembly 10 can select the mating connection position according to the required width dimension (i.e., the dimension of the first upper frame assembly 110 and the second upper frame assembly 120 in the relative direction, i.e., the dimension in the X-axis direction). Similarly, since the first lower frame assembly 210 and the second lower frame assembly 220 also have multiple mating connection positions, during the assembly stage, the lower mounting bracket assembly 20 can select the mating connection position according to the required width dimension (i.e., the dimension of the first lower frame assembly 210 and the second lower frame assembly 220 in the relative direction, i.e., the dimension in the X-axis direction). It can be understood that since the width dimensions of both the upper mounting bracket assembly 10 and the lower mounting bracket assembly 20 in the X-axis direction are selectable, it means that the overall width of the hinge mechanism 6 in the X-axis direction is adjustable. That is, the overall width of the hinge mechanism 6 can be flexibly and quickly adjusted according to different vehicle models, enabling different vehicle models to share a single hinge mechanism 6, thereby saving development costs and shortening the cycle.

[0065] In one embodiment, the first upper frame assembly 110 and the second upper frame assembly 120 are connected together by fasteners (such as screws, bolts, rivets, etc.). For example, the first upper frame assembly 110 has a first through hole, and the second upper frame assembly 120 has multiple second through holes. These multiple second through holes are spaced apart along the X-axis (the relative direction of the first upper frame assembly 110 and the second upper frame assembly 120). The first through hole is aligned with any one of the second through holes, and fasteners are used to pass through both the first and second through holes to connect the first upper frame assembly 110 and the second upper frame assembly 120 together. In this embodiment, the number of mating connection positions of the first upper frame assembly 110 and the second upper frame assembly 120 is equal to the number of second through holes. For example, if there are three second through holes, then there are three alignment forms between the first and second through holes, resulting in three mating connection positions. Therefore, multiple second through holes represent multiple alignment forms between the first and second through holes. It is understandable that, since multiple second through holes are arranged at intervals along the X-axis, the width dimension of the upper mounting bracket assembly 10 in the X-axis direction is different when the first through hole is aligned with different second through holes.

[0066] In another embodiment, the first upper frame assembly 110 and the second upper frame assembly 120 are snap-fitted together. The first upper frame assembly 110 and the second upper frame assembly 120 have multiple snap-fit ​​positions, allowing the dimensions of the upper mounting bracket assembly 10 to be adjustable in the relative directions of the first upper frame assembly 110 and the second upper frame assembly 120. The relevant structural design of the snap-fit ​​is described below with reference to the accompanying drawings.

[0067] Please refer to Figure 5 The first upper frame assembly 110 includes a first upper connector 111, a first upper bracket 112, and a first upper extension 113. The first upper connector 111 is connected to the first upper bracket 112, the first upper bracket 112 is connected to the first upper extension 113, and the first upper extension 113 is hinged to the first lower frame assembly 210. The first upper connector 111, the first upper bracket 112, and the first upper extension 113 can be made of the same material or different materials. The first upper connector 111 and the first upper bracket 112 can be an integral structure or a separate structure. Optionally, the first upper connector 111 and the first upper bracket 112 are separate structures, and the first upper connector 111 and the first upper bracket 112 are connected together by a snap-fit ​​method.

[0068] Please refer to Figure 5The second upper frame assembly 120 includes a second upper connector 121, a second upper support 122, and a second upper extension 123. The second upper connector 121 is connected to the second upper support 122, the second upper support 122 is connected to the second upper extension 123, and the second upper extension 123 is hinged to the second lower frame assembly 220. The second upper connector 121, the second upper support 122, and the second upper extension 123 can be made of the same material or different materials. The second upper connector 121 and the second upper support 122 can be an integral structure or a separate structure. Optionally, the second upper connector 121 and the second upper support 122 are separate structures, and the second upper connector 121 and the second upper support 122 are connected together by a snap-fit ​​method.

[0069] Optionally, the first upper connector 111 and the second upper connector 121 are detachably connected. The so-called detachable connection means that the first upper connector 111 and the second upper connector 121 can be separated or fixedly connected together.

[0070] Please refer to Figure 6 and Figure 7 The first upper connector 111 is provided with a plurality of first card interfaces X2, which are arranged at intervals along the relative direction (i.e., the X-axis direction) between the first upper frame assembly 110 and the second upper frame assembly 120. The second upper connector 121 is provided with a first card connector 1212c, which is snapped into any one of the first card interfaces X2.

[0071] The number of first card interfaces X2 can be 2, 3, 4, 5, etc., and is not limited here. This utility model only illustrates 3. The number of first card interfaces X2 is the number of snap-fit ​​positions. For example, 3 first card interfaces X2 means that the first upper frame assembly 110 and the second upper frame assembly 120 have 3 snap-fit ​​positions. Since the multiple first card interfaces X2 are arranged at intervals along the X-axis, the width dimension of the upper mounting frame assembly 10 in the X-axis direction is different when the first card connector 1212c is snapped into different first card interfaces X2. When it is necessary to place the first card connector 1212c into the required first card interface X2, it is only necessary to move the first upper connector 111 and the second upper connector 121 relative to each other in the X-axis direction. That is to say, during the assembly process, the first card connector 1212c can be selectively snapped into any one of the first card interfaces X2 according to the width requirement of the upper mounting frame assembly 10 in the X-axis direction.

[0072] Optionally, the spacing between adjacent first card interfaces X2 is 3mm to 10mm, and the spacing can be 3mm, 3.5mm, 4mm, 4.3mm, 5mm, 5.3mm, 6mm, 6.6mm, 7mm, 7.8mm, 8mm, 8.8mm, 9mm, 9.5mm, 10mm, etc.

[0073] Optionally, the first upper connector 111 is provided with three first card interfaces X2, namely a first card slot X21, a second card slot X22, and a third card slot X23, which are arranged sequentially at intervals along the positive X-axis. When the first card connector 1212c is engaged in the first card slot X21, the width dimension of the upper mounting bracket assembly 10 in the X-axis direction is the first dimension; when the first card connector 1212c is engaged in the second card slot X22, the width dimension of the upper mounting bracket assembly 10 in the X-axis direction is the second dimension; and when the first card connector 1212c is engaged in the third card slot X23, the width dimension of the upper mounting bracket assembly 10 in the X-axis direction is the third dimension. The first, second, and third dimensions increase sequentially. During assembly, depending on the width requirement of the upper mounting bracket assembly 10, the first snap-fit ​​connector 1212c can be selectively snapped into the first snap-fit ​​slot X21, the second snap-fit ​​slot X22, or the third snap-fit ​​slot X23. This allows it to be adapted to the armrest box 3 specifications of different car models, thus avoiding the problems of increased costs and longer cycle caused by the need to develop multiple molds.

[0074] Please refer to Figure 7 The first upper connector 111 has a receiving space X3, which is connected to the first card interface X2. The second upper connector 121 includes a main body 1211 and a plug-in part 1212 connected to each other. The plug-in part 1212 has a first card connector 1212c. The plug-in part 1212 is inserted into the receiving space X3 so that the first card connector 1212c is engaged in the first card interface X2.

[0075] Both the main body 1211 and the insertion part 1212 are generally plate-shaped. The shape and size of the insertion part 1212 match the shape and size of the receiving space X3, allowing the insertion part 1212 to be inserted into the receiving space X3, while the main body 1211 cannot be inserted into the receiving space X3. It is understandable that if the first upper connector 111 and the second upper connector 121 are connected only through the first snap-fit ​​connector 1212c and the first snap-fit ​​interface X2, the connection strength is relatively low and easily damaged. In this embodiment, the insertion part 1212 is provided on the second upper connector 121, and the insertion part 1212 is inserted into the receiving space X3 of the first upper connector 111. This makes it less likely for the first upper connector 111 and the second upper connector 121 to be bent relative to each other, thereby improving the connection strength between the two.

[0076] Please refer to Figure 8 The insertion part 1212 includes an insertion body 1212a and a deformation part 1212b. The deformation part 1212b is elongated, and its two opposite ends along its length are connected to the insertion body 1212a, forming a deformation space X4 together with the insertion body 1212a. The first card connector 1212c protrudes from the side of the deformation part 1212b opposite to the deformation space X4. The deformation space X4 is used to allow the deformation part 1212b to deform, so that the first card connector 1212c can move in the direction of the deformation space X4, thereby smoothly entering or exiting the first card interface X2.

[0077] Specifically, the first snap-fit ​​connector 1212c has a first surface M1, a second surface M2, and a third surface M3 (e.g., ...). Figure 8As shown, the first surface M1, the second surface M2, and the third surface M3 are sequentially bent and connected. The first surface M1 is inclined relative to the deformable portion 1212b, meaning it is an inclined surface on the first snap-fit ​​connector 1212c. The second surface M2 is the surface of the first snap-fit ​​connector 1212c facing away from the deformable space X4, and it can be parallel to the deformable portion 1212b. The third surface M3 is closer to the main body 1211 than the first surface M1, and it can be perpendicular to the deformable portion 1212b. During the insertion of the connector 1212 into the receiving space X3 along the first direction (the direction of the main body 1211 toward the connector 1212), the sidewall of the receiving space X3 first abuts against the first surface M1 and is guided from the first surface M1 to the second surface M2. The first snap-fit ​​connector 1212c presses against the deformable part 1212b, causing the deformable part 1212b to bend toward the deformable space X4, thus allowing the connector 1212 to continue to be inserted along the first direction. When the first snap-fit ​​connector 1212c reaches the first first snap-fit ​​interface X2, the deformable part 1212b returns to its original shape, thereby driving the first snap-fit ​​connector 1212c into the first snap-fit ​​interface X2. Inside the X2, the third surface M3 is in contact with the wall of the first card interface X2, preventing the insertion part 1212 from retracting in the second direction (the second direction is the opposite of the first direction), that is, the second upper connector 121 cannot detach from the first upper connector 111; when it is necessary to remove the first card connector 1212c from the first card interface X2, the second surface M2 can be pressed, and the first card connector 1212c presses the deformable part 1212b, causing the deformable part 1212b to bend towards the deformation space X4, thereby removing the first card connector 1212c from the first card interface X2. At this time, the insertion part 1212 can move along the first direction or the second direction.

[0078] Please refer to Figure 5 The first lower frame assembly 210 includes a first lower connector 211 and a first lower support 212. The first lower connector 211 is connected to the first lower support 212, and the first lower support 212 is hinged to the first upper extension 113. The first lower connector 211 and the first lower support 212 can be made of the same material or different materials. The first lower connector 211 and the first lower support 212 can be an integral structure or a separate structure. Optionally, the first lower connector 211 and the first lower support 212 are separate structures, and the first lower connector 211 and the first lower support 212 are connected together by a snap-fit ​​method.

[0079] Please refer to Figure 5The second lower frame assembly 220 includes a second lower connector 221 and a second lower support 222. The second lower connector 221 is connected to the second lower support 222, and the second lower support 222 is hinged to the second upper extension 123. The second lower connector 221 and the second lower support 222 can be made of the same material or different materials. The second lower connector 221 and the second lower support 222 can be an integral structure or a separate structure. Optionally, the second lower connector 221 and the second lower support 222 are separate structures, and the second lower connector 221 and the second lower support 222 are connected together by a snap-fit ​​method.

[0080] Optionally, the first lower connector 211 and the second lower connector 221 are detachably connected. The so-called detachable connection means that the first lower connector 211 and the second lower connector 221 can be separated or fixedly connected together.

[0081] Optionally, the first lower connector 211 is provided with a plurality of second locking interfaces, which are arranged at intervals along the relative direction (i.e., the X-axis direction) between the first lower frame assembly 210 and the second lower frame assembly 220. The second lower connector 221 is provided with a second locking head, which is engaged with any one of the second locking interfaces. During assembly, the second locking head can be selectively engaged with any one of the second locking interfaces according to the required width of the lower mounting frame assembly 20 in the X-axis direction.

[0082] Regarding the specific details of the adjustable width structure in the lower mounting bracket assembly 20, the same structure as the upper mounting bracket assembly 10 can be adopted. For details, please refer to the accompanying drawings and corresponding descriptions in the previous embodiment of the upper mounting bracket assembly 10; further details will not be provided here. It is understood that by coordinating and adjusting the upper mounting bracket assembly 10 and the lower mounting bracket assembly 20, the overall width of the hinge mechanism 6 in the X-axis direction can be adjusted.

[0083] Part Two: Height Adjustable Hinge Mechanism

[0084] Please refer to Figure 9 and Figure 10 The first upper frame assembly 110 includes a first upper support 112 and a first upper extension 113. The first upper support 112 is directly or indirectly connected to the second upper frame assembly 120. The first upper extension 113 is hinged to the first lower frame assembly 210. The first upper support 112 is connected to the first upper extension 113, and the first upper support 112 and the first upper extension 113 have multiple mating connection positions, allowing the first upper support 112 to be close to or away from the first lower frame assembly 210.

[0085] In other words, there are two or more mating connection points between the first upper bracket 112 and the first upper extension 113. The first upper bracket 112 and the first upper extension 113 are fixedly connected through any one of these mating connection points. Furthermore, when the first upper bracket 112 and the first upper extension 113 are fixedly connected through different mating connection points, the corresponding dimensions of the first upper frame assembly 110 in the Y-axis direction are different. Therefore, during the assembly stage, the appropriate mating connection point can be selected based on the determined dimensions of the first upper frame assembly 110 in the Y-axis direction.

[0086] Please refer to Figure 9 and Figure 10 The second upper frame assembly 120 includes a second upper support 122 and a second upper extension 123. The second upper support 122 is directly or indirectly connected to the first upper frame assembly 110. The second upper extension 123 is hinged to the second lower frame assembly 220. The second upper support 122 is connected to the second upper extension 123, and the second upper support 122 and the second upper extension 123 have multiple mating connection positions, allowing the second upper support 122 to be close to or away from the second lower frame assembly 220.

[0087] In other words, there are two or more mating connection points between the second upper bracket 122 and the second upper extension 123. The second upper bracket 122 and the second upper extension 123 are fixedly connected through any one of these mating connection points. Furthermore, when the second upper bracket 122 and the second upper extension 123 are fixedly connected through different mating connection points, the corresponding dimensions of the second upper frame assembly 120 in the Y-axis direction are different. Therefore, during the assembly stage, the appropriate mating connection point can be selected based on the determined dimensions of the second upper frame assembly 120 in the Y-axis direction.

[0088] In summary, in the hinge mechanism 6 provided by this utility model, since the first upper bracket 112 and the second upper extension 123 have multiple mating connection positions, during the assembly stage, the first upper frame assembly 110 can select the mating connection position according to the required height dimension (i.e., the dimension in the Y-axis direction). Similarly, since the second upper bracket 122 and the second upper extension 123 have multiple mating connection positions, during the assembly stage, the second upper frame assembly 120 can select the mating connection position according to the required height dimension (i.e., the dimension in the Y-axis direction). It can be understood that since both the first upper frame assembly 110 and the second upper frame assembly 120 have selectable height dimensions in the Y-axis direction, it means that the overall height of the hinge mechanism 6 in the Y-axis direction is adjustable. That is, the overall height of the hinge mechanism 6 can be flexibly and quickly adjusted according to different vehicle models, enabling different vehicle models to share a single hinge mechanism 6, thereby saving development costs and shortening the cycle.

[0089] Please refer to Figure 11 and Figure 12 In one embodiment, the first upper bracket 112 includes a first bracket portion 1121 and a second bracket portion 1122 bent and connected together. The first bracket portion 1121 is directly or indirectly connected to the second upper frame assembly 120, and the second bracket portion 1122 is connected to the first upper extension member 113. The second bracket portion 1122 is provided with a plurality of first mounting holes X5, and the distance from each first mounting hole X5 to the first bracket portion 1121 is different. The first upper extension member 113 is provided with a plurality of second mounting holes X6, the arrangement direction of the plurality of second mounting holes X6 is the same as the arrangement direction of the plurality of first mounting holes X5, and the spacing distance between two adjacent second mounting holes X6 is the same as the spacing distance between two adjacent first mounting holes X5, so that at least one pair of first mounting holes X5 and second mounting holes X6 are arranged opposite each other to allow fasteners 130 to pass through.

[0090] Specifically, the number of first mounting holes X5 is greater than or equal to two, specifically two, three, four, etc. The first mounting holes X5 can be round, square, oval, etc. The number of second mounting holes X6 is the same as the number of first mounting holes X5. The shape of the second mounting holes X6 is the same as the shape of the first mounting holes X5. It is understood that since the arrangement direction and spacing of the first mounting holes X5 and second mounting holes X6 are the same, at least one pair of first mounting holes X5 and second mounting holes X6 can be paired (i.e., relatively arranged). Then, fasteners 130 (such as rivets, bolts, etc.) pass through the paired first mounting holes X5 and second mounting holes X6, connecting the second bracket part 1122 and the first upper extension 113. During assembly, the number of pairs of first mounting holes X5 and second mounting holes X6 can be selected along the arrangement direction of the mounting holes, thereby changing the dimension of the first upper frame assembly 110 in the Y-axis direction.

[0091] The example is illustrated with three first mounting holes X5 and three second mounting holes X6. When three pairs of first mounting holes X5 and second mounting holes X6 are paired, the dimension of the first upper frame assembly 110 in the Y-axis direction is the third height, as shown below. Figure 9 and Figure 12 As shown. When two pairs of first mounting holes X5 and second mounting holes X6 are paired, the dimension of the first upper frame assembly 110 in the Y-axis direction is the second height, as shown. Figure 10 and Figure 13 As shown. When only one pair of first mounting holes X5 and second mounting holes X6 are paired, the dimension of the first upper frame assembly 110 in the Y-axis direction is the first height, as shown. Figure 14 As shown in the diagram, the first, second, and third altitudes decrease sequentially.

[0092] Please refer to Figures 15 to 18 In another embodiment, the first upper bracket 112 includes a first bracket portion 1121 and a second bracket portion 1122 that are bent and connected together. The first bracket portion 1121 is directly or indirectly connected to the second upper frame assembly 120. The second bracket portion 1122 is connected to the first upper extension member 113. The second bracket portion 1122 has a plurality of first mounting holes X5, each at a different distance from the first bracket portion 1121. The first upper extension member 113 has a second mounting hole X6, which is opposite to any one of the first mounting holes X5 for a fastener 130 to pass through, thereby forming a fixed connection between the second bracket portion 1122 and the first upper extension member 113.

[0093] Specifically, the number of first mounting holes X5 is two or more, specifically two, three, four, etc. Both the first mounting holes X5 and the second mounting holes X6 can be round, square, elliptical, etc. The second mounting hole X6 can be paired with any one of the first mounting holes X5 (i.e., relative to each other), and then fasteners 130 (such as rivets, bolts, etc.) pass through the paired first mounting holes X5 and second mounting holes X6, thus connecting the second bracket portion 1122 and the first upper extension member 113. It is understood that since the distance from each first mounting hole X5 to the first bracket portion 1121 is different, when the second mounting hole X6 is paired with different first mounting holes X5, the distance from the first upper extension member 113 to the first bracket portion 1121 will be different, meaning the height dimension of the first upper frame assembly 110 in the Y-axis direction will be different. When the second mounting hole X6 mates with the first mounting hole X5 near the first bracket portion 1121, the dimension of the first upper frame assembly 110 in the Y-axis direction decreases; when the second mounting hole X6 mates with the first mounting hole X5 away from the first bracket portion 1121, the dimension of the first upper frame assembly 110 in the Y-axis direction increases, such as... Figures 16 to 18 As shown.

[0094] Please refer to Figures 19 to 22In another embodiment, the first upper bracket 112 includes a first bracket portion 1121 and a second bracket portion 1122 that are bent and connected together. The first bracket portion 1121 is directly or indirectly connected to the second upper frame assembly 120. The second bracket portion 1122 is connected to the first upper extension member 113. The second bracket portion 1122 is provided with a first mounting hole X5. The first upper extension member 113 is provided with a plurality of second mounting holes X6, each at a different distance from the first bracket portion 1121. The first mounting hole X5 is positioned opposite to any one of the second mounting holes X6 to allow a fastener 130 to pass through, thereby forming a fixed connection between the second bracket portion 1122 and the first upper extension member 113.

[0095] Specifically, the number of second mounting holes X6 is greater than or equal to two, specifically two, three, four, etc. Both the first mounting hole X5 and the second mounting hole X6 can be round, square, elliptical, etc. The first mounting hole X5 can be paired with any one of the second mounting holes X6 (i.e., relative to each other), and then fasteners 130 (such as rivets, bolts, etc.) pass through the paired first mounting holes X5 and X6, thus connecting the second bracket portion 1122 and the first upper extension member 113. It is understood that since the distance from each second mounting hole X6 to the first bracket portion 1121 is different, when the first mounting hole X5 is paired with different second mounting holes X6, the distance from the first upper extension member 113 to the first bracket portion 1121 will be different, meaning the height dimension of the first upper frame assembly 110 in the Y-axis direction will be different. When the first mounting hole X5 mates with the second mounting hole X6 near the first bracket portion 1121, the dimension of the first upper frame assembly 110 in the Y-axis direction decreases; when the first mounting hole X5 mates with the second mounting hole X6 away from the first bracket portion 1121, the dimension of the first upper frame assembly 110 in the Y-axis direction increases, such as... Figures 20 to 22 .

[0096] Regarding the specific details of the height-adjustable structure in the second upper frame assembly 120, the same structure as the first upper frame assembly 110 can be adopted. For details, please refer to the accompanying drawings and corresponding descriptions in the previous embodiment of the first upper frame assembly 110; further details will not be provided here. It is understood that by coordinating and adjusting the first upper frame assembly 110 and the second upper frame assembly 120, the overall height of the hinge mechanism 6 in the Y-axis direction can be adjusted.

[0097] Please refer to Figure 23The hinge mechanism 6 further includes a first hinge assembly 30 and a second hinge assembly 40. The first upper frame assembly 110 and the first lower frame assembly 210 are hinged together by the first hinge assembly 30. The second upper frame assembly 120 and the second lower frame assembly 220 are hinged together by the second hinge assembly 40. Specifically, the first lower support 212 and the first upper extension 113 are hinged together by the first hinge assembly 30. The second lower support 222 and the second upper extension 123 are hinged together by the second hinge assembly 40.

[0098] Optionally, the first hinge assembly 30 includes a first hinge pin 310, a first brass washer 320, a first stainless steel washer 330, and a first corrugated washer 340. The first brass washer 320, the first upper extension 113, the first stainless steel washer 330, the first lower bracket 212, and the first corrugated washer 340 are arranged sequentially, and the first hinge pin 310 passes through a brass washer, the first upper extension 113, the first stainless steel washer 330, the first lower bracket 212, and the first corrugated washer 340, so that the first lower bracket 212 is hinged together with the first upper extension 113.

[0099] Optionally, the second hinge assembly 40 includes a second hinge pin, a second brass washer, a second stainless steel washer, and a second corrugated washer. The second brass washer, the second upper extension 123, the second stainless steel washer, the second lower bracket 222, and the second corrugated washer are arranged sequentially, and the second hinge pin passes through a brass washer, the second upper extension 123, the second stainless steel washer, the second lower bracket 222, and the second corrugated washer, so that the second lower bracket 222 is hinged together with the second upper extension 123.

[0100] In the first hinge assembly 30, the first brass washer 320 is relatively soft and is used to reduce frictional noise during the rotation of the first upper extension 113 relative to the first lower support 212. The first stainless steel washer 330 is used to improve wear resistance and durability, and the first corrugated washer 340 is used to provide axial preload so that the first upper extension 113 can be suspended at any position during rotation relative to the first lower support 212. The second hinge assembly 40 is similar and will not be described in detail here.

[0101] Please refer to Figure 23The first lower support 212 includes a first sub-part 2121, a second sub-part 2122, and a third sub-part 2123 connected in sequence by bending. The first sub-part 2121 is connected to the first lower connector 211, the second sub-part 2122 is hinged to the first upper extension 113, and the third sub-part 2123 is located on the rotation path of the first upper frame assembly 110. The first lower frame assembly 210 may also include a first buffer pad 213. The third sub-part 2123 is provided with the first buffer pad 213, which can be made of rubber with a certain degree of elasticity. When the first upper frame assembly 110 impacts the first buffer pad 213 during rotation, the first buffer pad 213 can absorb energy, thereby reducing impact noise.

[0102] Please refer to Figure 23 The second lower frame assembly 220 may further include a second buffer pad 223. The first lower support 212 is provided with the second buffer pad 223, which is located on the rotation path of the second upper frame assembly 120. The second buffer pad 223 can be made of rubber with a certain degree of elasticity. When the second upper frame assembly 120 impacts the second buffer pad 223 during rotation, the second buffer pad 223 can absorb energy, thereby reducing impact noise.
