Detailed implementation mode

[0052] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0053] Referring to "embodiment" or "implementation mode" herein means that a specific feature, structure or characteristic described in connection with the embodiment or implementation mode can be included in at least one embodiment of the present invention. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0054] Please refer to Figure 1, the present invention also provides a vehicle 1, which may be, but is not limited to, a sedan, a station wagon, an MPV, an SUV, a sports car, a pickup truck, a minivan, a bus, etc. The vehicle 1 includes a body device 2 and an armrest box 3. The body device 2 has an interior space X1, and the armrest box 3 is disposed within the interior space X1.

[0055] 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 body 5, and a hinge mechanism 6 described in any embodiment of the present invention. The cover body 5 is connected to the upper mounting frame assembly 10 of the hinge mechanism 6, and the box body 4 is connected to the lower mounting frame assembly 20 of the hinge mechanism 6, so that the cover body 5 can rotate relative to the box body 4.

[0056] The box body 4 has a storage space where items can be placed. The cover body 5 can be opened and closed relative to the box body 4 by rotation, and the cover body 5 is used to cover the storage space or support the driver's elbow. The armrest box 3 has an open state (not shown) and a closed state (as shown in Figure 2 ), when the armrest box 3 is in the open state, the box body 4 and the cover body 5 form a certain angle, and the storage space of the box body 4 is not blocked by the cover body 5; when the armrest box 3 is in the closed state, the cover body 5 covers the box body 4, and the storage space of the box body 4 is blocked by the cover body 5.

[0057] Please refer to Figure 3 , the present invention provides a hinge mechanism 6, which can achieve adjustable width and adjustable height to adapt to the specifications of armrest boxes 3 of different vehicle models.

[0058] It should be noted that the so-called adjustable width (or height) in the present invention means that during the assembly stage of the hinge mechanism 6, hinge mechanisms 6 with different width (or height) dimensions can be assembled according to requirements, rather than implying that the width (or height) dimension of the hinge mechanism 6 can still be adjusted after assembly. Whether the width (or height) dimension of the hinge mechanism 6 can be adjusted after assembly is not limited herein.

[0059] For ease of reading and understanding, the following is divided into two parts to introduce the adjustable width and adjustable height of the hinge mechanism 6 respectively. On the premise of no combination obstacle, any embodiment in the two parts can be combined, and it should not be regarded that the two parts are separated and cannot be combined.

[0060] For ease of subsequent description, take Figure 3The perspective shown defines a right-handed rectangular coordinate system in the XYZ space. Among them, the X-axis is parallel to the width direction of the hinge mechanism 6, the Y-axis is parallel to the height direction of the hinge mechanism 6, and the Z-axis is parallel to the thickness direction of the hinge mechanism 6. The directions indicated by the arrows of the X / Y / Z axes are the positive directions of the X / Y / Z axes, and the opposite directions of the directions indicated by the arrows of the X / Y / Z axes are the negative directions of the X / Y / Z axes. Please refer to this for the following descriptions related to the coordinate system.

[0061] Part 1: Adjustable width of the hinge mechanism

[0062] Please refer to Figure 3 , the hinge mechanism 6 includes: an upper mounting frame assembly 10 and a lower mounting frame assembly 20. The upper mounting frame assembly 10 is hinged to the lower mounting frame assembly 20, that is, the upper mounting frame assembly 10 can rotate relative to the lower mounting frame assembly 20.

[0063] Please refer to Figure 4 , the upper mounting frame assembly 10 includes: a first upper frame body assembly 110 and a second upper frame body assembly 120. Among them, the second upper frame body assembly 120 is connected to the first upper frame body assembly 110. And the first upper frame body assembly 110 and the second upper frame body assembly 120 have multiple mating connection positions, so that the size of the upper mounting frame assembly 10 in the relative direction of the first upper frame body assembly 110 and the second upper frame body assembly 120 (i.e., the X-axis direction) is adjustable. That is to say, the number of mating connection positions between the first upper frame body assembly 110 and the second upper frame body assembly 120 is greater than or equal to two. The first upper frame body assembly 110 and the second upper frame body assembly 120 form a fixed connection through any one of the mating connection positions. And when the first upper frame body assembly 110 and the second upper frame body assembly 120 form a fixed connection through different mating connection positions, the corresponding size of the upper mounting frame assembly 10 in the X-axis direction is different. Therefore, during the assembly stage, the corresponding mating connection position can be selected according to the size determined by the upper mounting frame assembly 10 in the X-axis direction.

[0064] Please refer to Figure 4, the lower mounting frame assembly 20 includes: a first lower frame body assembly 210 and a second lower frame body assembly 220. Among them, the first lower frame body assembly 210 is hinged to the first upper frame body assembly 110. The second lower frame body assembly 220 is hinged to the second upper frame body assembly 120. The second lower frame body assembly 220 is connected to the first lower frame body assembly 210. And the first lower frame body assembly 210 and the second lower frame body assembly 220 have a plurality of mating connection positions, so that the size of the lower mounting frame assembly 20 in the relative direction of the first lower frame body assembly 210 and the second lower frame body assembly 220 (i.e., the X-axis direction) is adjustable. That is to say, the number of mating connection positions between the first lower frame body assembly 210 and the second lower frame body assembly 220 is greater than or equal to two. The first lower frame body assembly 210 and the second lower frame body assembly 220 form a fixed connection through any one of the mating connection positions. Moreover, when the first lower frame body assembly 210 and the second lower frame body assembly 220 form a fixed connection through different mating connection positions, the corresponding size of the lower mounting frame assembly 20 in the X-axis direction is different. Therefore, during the assembly stage, the corresponding mating connection position can be selected according to the size determined by the lower mounting frame assembly 20 in the X-axis direction.

[0065] In summary, in the hinge mechanism 6 provided by the present invention, since the first upper frame body assembly 110 and the second upper frame body assembly 120 are provided with a plurality of mating connection positions, during the assembly stage, the upper mounting frame assembly 10 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 body assembly 110 and the second upper frame body assembly 120, that is, the dimension in the X-axis direction). Similarly, since the first lower frame body assembly 210 and the second lower frame body assembly 220 are also provided with a plurality of mating connection positions, during the assembly stage, the lower mounting frame assembly 20 can select the mating connection position according to the required width dimension (the dimension in the relative direction of the first lower frame body assembly 210 and the second lower frame body assembly 220, that is, the dimension in the X-axis direction). It can be understood that the width dimensions of the upper mounting frame assembly 10 and the lower mounting frame assembly 20 in the X-axis direction are both selectable, which 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 hinge mechanism 6, thereby saving development costs and shortening the cycle.

[0066] 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 illustrative purposes, the first upper frame assembly 110 is provided with a first through hole, and the second upper frame assembly 120 is provided with a plurality of second through holes. The plurality of second through holes are arranged at intervals along the X-axis direction (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 a fastener is used to pass through the first through hole and the second through hole, so that the first upper frame assembly 110 and the second upper frame assembly 120 are connected together. In this embodiment, the number of mating connection positions between 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 the number of second through holes is three, then there are three alignment forms between the first through hole and the second through hole, and the number of mating connection positions is three. Therefore, the plurality of second through holes represent multiple alignment forms between the first through hole and the second through hole. It can be understood that since the plurality of second through holes are arranged at intervals along the X-axis direction, the width dimensions of the upper mounting frame assembly 10 corresponding to the alignment of the first through hole with different second through holes are different in the X-axis direction.

[0067] In another embodiment, the first upper frame assembly 110 and the second upper frame assembly 120 are snap-fitted. The first upper frame assembly 110 and the second upper frame assembly 120 have a plurality of snap-fitting positions, so that the size of the upper mounting frame assembly 10 in the relative direction of the first upper frame assembly 110 and the second upper frame assembly 120 is adjustable. The following introduces the related structural design of the snap fit in conjunction with the drawings.

[0068] Please refer to Figure 5 , the first upper frame assembly 110 includes a first upper connecting member 111, a first upper bracket 112, and a first upper extension member 113. Among them, the first upper connecting member 111 is connected to the first upper bracket 112, the first upper bracket 112 is connected to the first upper extension member 113, and the first upper extension member 113 is hinged to the first lower frame assembly 210. The first upper connecting member 111, the first upper bracket 112, and the first upper extension member 113 can be made of the same material or different materials. The first upper connecting member 111 and the first upper bracket 112 can be of an integral structure or a split structure. Optionally, the first upper connecting member 111 and the first upper bracket 112 are of a split structure, and the first upper connecting member 111 and the first upper bracket 112 are connected together by snap-fitting.

[0069] Please refer to Figure 5, the second upper frame component 120 includes a second upper connecting member 121, a second upper bracket 122, and a second upper extension member 123. Among them, the second upper connecting member 121 is connected to the second upper bracket 122, the second upper bracket 122 is connected to the second upper extension member 123, and the second upper extension member 123 is hinged to the second lower frame component 220. The second upper connecting member 121, the second upper bracket 122, and the second upper extension member 123 can be made of the same material or different materials. The second upper connecting member 121 and the second upper bracket 122 can be an integral structure or a split structure. Optionally, the second upper connecting member 121 and the second upper bracket 122 are of a split structure, and the second upper connecting member 121 and the second upper bracket 122 are connected together by a snap connection.

[0070] Optionally, the first upper connecting member 111 and the second upper connecting member 121 are detachably connected. The so-called detachable connection means that the first upper connecting member 111 and the second upper connecting member 121 can be separated or fixedly connected together.

[0071] Please refer to Figure 6 and Figure 7 , the first upper connecting member 111 is provided with a plurality of first card interfaces X2, and the plurality of first card interfaces X2 are arranged at intervals along the relative direction (i.e., the X-axis direction) of the first upper frame component 110 and the second upper frame component 120. The second upper connecting member 121 is provided with a first card joint 1212c, and the first card joint 1212c is snapped into any one of the first card interfaces X2.

[0072] Among them, the number of the first card interfaces X2 can be 2, 3, 4, 5, etc., which is not limited here. In the present invention, only 3 are used for illustration. The number of the first card interfaces X2 is the number of the snap-fit positions. For example, 3 first card interfaces X2 means that the first upper frame component 110 and the second upper frame component 120 have 3 snap-fit positions. Since the plurality of first card interfaces X2 are arranged at intervals along the X-axis direction, when the first card joint 1212c is snapped into different first card interfaces X2, the width dimensions of the upper mounting frame component 10 in the X-axis direction are different. When it is necessary to place the first card joint 1212c into the required first card interface X2, only the first upper connecting member 111 and the second upper connecting member 121 need to move relative to each other in the X-axis direction. That is to say, during the assembly process, according to the width requirement of the upper mounting frame component 10 in the X-axis direction, the first card joint 1212c can be selectively snapped into any one of the first card interfaces X2.

[0073] Optionally, the spacing distance between adjacent first card interfaces X2 is 3 mm to 10 mm. This spacing distance can be 3 mm, 3.5 mm, 4 mm, 4.3 mm, 5 mm, 5.3 mm, 6 mm, 6.6 mm, 7 mm, 7.8 mm, 8 mm, 8.8 mm, 9 mm, 9.5 mm, 10 mm, etc.

[0074] Optionally, the first upper connecting member 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. The first card slot X21, the second card slot X22, and the third card slot X23 are arranged at intervals in the positive X-axis direction in sequence. When the first card joint 1212c is clamped in the first card slot X21, the width dimension of the upper mounting frame assembly 10 in the X-axis direction is the first dimension; when the first card joint 1212c is clamped in the second card slot X22, the width dimension of the upper mounting frame assembly 10 in the X-axis direction is the second dimension; when the first card joint 1212c is clamped in the third card slot X23, the width dimension of the upper mounting frame assembly 10 in the X-axis direction is the third dimension. Among them, the first dimension, the second dimension, and the third dimension increase in sequence. During the assembly process, according to the width requirement of the upper mounting frame assembly 10, the first card joint 1212c can be selectively clamped in the first card slot X21, or the second card slot X22, or the third card slot X23, so as to be adapted to the specifications of the armrest box 3 of different vehicle models, thereby avoiding the problems of increased cost and extended cycle caused by the need to develop multiple molds.

[0075] Please refer to Figure 7 , the first upper connecting member 111 is provided with a receiving space X3, and the receiving space X3 communicates with the first card interface X2. The second upper connecting member 121 includes a main body portion 1211 and a plugging portion 1212 connected to each other. The plugging portion 1212 is provided with the first card joint 1212c, and the plugging portion 1212 is inserted into the receiving space X3 so that the first card joint 1212c is clamped in the first card interface X2.

[0076] Among them, the main body 1211 and the plug-in part 1212 are both roughly plate-shaped, and the shape and size of the plug-in part 1212 match the shape and size of the accommodating space X3, so that the plug-in part 1212 can be inserted into the accommodating space X3, while the main body 1211 cannot be inserted into the accommodating space X3. It can be understood that if the first upper connecting member 111 and the second upper connecting member 121 are only connected by the first card connector 1212c and the first card interface X2, the strength of this connection form is relatively small and easy to damage. In this embodiment, the plug-in part 1212 is provided on the second upper connecting member 121, and the plug-in part 1212 is inserted into the accommodating space X3 of the first upper connecting member 111, so that the first upper connecting member 111 and the second upper connecting member 121 are not easy to bend relative to each other, thereby improving the connection strength between the two.

[0077] Please refer to Figure 8 The plug-in portion 1212 includes a plug-in body 1212a and a deformation portion 1212b, wherein the deformation portion 1212b is in the shape of a long strip, and both opposite ends of the deformation portion 1212b in the length direction are connected to the plug-in body 1212a, so as to form a deformation space X4 together with the plug-in body 1212a. The first card connector 1212c is convexly arranged on the side of the deformation portion 1212b away from the deformation space X4. The deformation space X4 is used for the deformation portion 1212b to deform, so that the first card connector 1212c can move in the direction of the deformation space X4, thereby smoothly entering the first card interface X2 or exiting from the first card interface X2.

[0078] Specifically, the first clamping joint 1212c has a first surface M1, a second surface M2, and a third surface M3 (eg Figure 8As shown in the figure, the first surface M1, the second surface M2, and the third surface M3 are bent and connected in sequence. Among them, the first surface M1 is inclined relative to the deformation portion 1212b, that is, the first surface M1 is an inclined surface on the first clamping joint 1212c. The second surface M2 is the surface of the first clamping joint 1212c on the side away from the deformation space X4, and the second surface M2 can be parallel to the deformation portion 1212b. The third surface M3 is closer to the main body 1211 than the first surface M1, and the third surface M3 can be perpendicular to the deformation portion 1212b. When the plug-in portion 1212 is inserted into the accommodating space X3 along the first direction (the direction in which the main body 1211 is toward the plug-in portion 1212), the side wall of the accommodating space X3 first abuts against the first surface M1, and is guided from the first surface M1 to the second surface M2. The first card connector 1212c presses the deformation portion 1212b, so that the deformation portion 1212b bends toward the deformation space X4, and the plug-in portion 1212 is able to continue to be inserted along the first direction; when the first card connector 1212c reaches the first first card interface X2, the deformation portion 1212b returns to its original state, thereby driving the first card connector 1212c to enter the first card interface X2. In the opening X2, the third surface M3 is in contact with the wall of the first card interface X2, so that the plug-in portion 1212 cannot retreat in the second direction (the second direction is the opposite direction of the first direction), that is, the second upper connecting member 121 cannot be separated from the first upper connecting member 111; when it is necessary to withdraw the first card connector 1212c from the first card interface X2, the second surface M2 can be pressed, and the first card connector 1212c compresses the deformation portion 1212b, so that the deformation portion 1212b bends toward the deformation space X4, and the first card connector 1212c thereby withdraws from the first card interface X2, and the plug-in portion 1212 can move along the first direction or the second direction.

[0079] Please refer to Figure 5 The first lower frame assembly 210 includes a first lower connecting member 211 and a first lower bracket 212. The first lower connecting member 211 is connected to the first lower bracket 212, and the first lower bracket 212 is hinged to the first upper extension member 113. The first lower connecting member 211 and the first lower bracket 212 can be made of the same material or different materials. The first lower connecting member 211 and the first lower bracket 212 can be an integrated structure or a split structure. Optionally, the first lower connecting member 211 and the first lower bracket 212 are a split structure, and the first lower connecting member 211 and the first lower bracket 212 are connected together by a snap-fitting manner.

[0080] Please refer to Figure 5, the second lower frame assembly 220 includes a second lower connecting member 221 and a second lower bracket 222. Among them, the second lower connecting member 221 is connected to the second lower bracket 222, and the second lower bracket 222 is hinged to the second upper extension member 123. The second lower connecting member 221 and the second lower bracket 222 can be of the same material or different materials. The second lower connecting member 221 and the second lower bracket 222 can be of an integral structure or a split structure. Optionally, the second lower connecting member 221 and the second lower bracket 222 are of a split structure, and the second lower connecting member 221 and the second lower bracket 222 are connected together by a snap connection.

[0081] Optionally, the first lower connecting member 211 and the second lower connecting member 221 are detachably connected. The so-called detachable connection means that the first lower connecting member 211 and the second lower connecting member 221 can be separated or fixedly connected together.

[0082] Optionally, the first lower connecting member 211 is provided with a plurality of second card interfaces, and the plurality of second card interfaces are arranged at intervals along the relative direction (i.e., the X-axis direction) of the first lower frame assembly 210 and the second lower frame assembly 220. The second lower connecting member 221 is provided with a second card joint, and the second card joint is snapped into any one of the second card interfaces. During the assembly process, according to the width requirement of the lower mounting frame assembly 20 in the X-axis direction, the second card joint can be selectively snapped into any one of the second card interfaces.

[0083] Regarding the specific details of the relevant structure for realizing the adjustable width in the lower mounting frame assembly 20, the same structure as that of the upper mounting frame assembly 10 can be adopted. Specifically, reference can be made to the drawings and corresponding descriptions in the foregoing embodiments of the upper mounting frame assembly 10, and details will not be described herein again. It can be understood that by the cooperation and adjustment of the upper mounting frame assembly 10 and the lower mounting frame assembly 20, the overall width of the hinge mechanism 6 in the X-axis direction can be adjusted.

[0084] Part Two: Adjustable Height of the Hinge Mechanism

[0085] Please refer to Figure 9 and Figure 10 , the first upper frame assembly 110 includes a first upper bracket 112 and a first upper extension member 113. Among them, the first upper bracket 112 is directly or indirectly connected to the second upper frame assembly 120. The first upper extension member 113 is hinged to the first lower frame assembly 210. The first upper bracket 112 is connected to the first upper extension member 113, and the first upper bracket 112 and the second upper extension member 123 have a plurality of mating connection positions, so that the first upper bracket 112 can approach or move away from the first lower frame assembly 210.

[0086] That is to say, the number of mating connection positions between the first upper support 112 and the first upper extension 113 is greater than or equal to two. The first upper support 112 and the first upper extension 113 are fixedly connected through any one of the mating connection positions. Moreover, when the first upper support 112 and the first upper extension 113 are fixedly connected through different mating connection positions, the dimensions of the corresponding first upper frame assembly 110 in the Y-axis direction are different. Therefore, during the assembly stage, the corresponding mating connection position can be selected according to the dimension of the first upper frame assembly 110 determined in the Y-axis direction.

[0087] 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. Wherein, 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, so that the second upper support 122 can approach or move away from the second lower frame assembly 220.

[0088] That is to say, the number of mating connection positions between the second upper support 122 and the second upper extension 123 is greater than or equal to two. The second upper support 122 and the second upper extension 123 are fixedly connected through any one of the mating connection positions. Moreover, when the second upper support 122 and the second upper extension 123 are fixedly connected through different mating connection positions, the dimensions of the corresponding second upper frame assembly 120 in the Y-axis direction are different. Therefore, during the assembly stage, the corresponding mating connection position can be selected according to the dimension of the second upper frame assembly 120 determined in the Y-axis direction.

[0089] In summary, in the hinge mechanism 6 provided by the present invention, since the first upper support 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 support 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 the height dimensions of the first upper frame assembly 110 and the second upper frame assembly 120 in the Y-axis direction are both selectable, which 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, so that different vehicle models can share a hinge mechanism 6, thereby saving development costs and shortening the cycle.

[0090] 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 that are bent and connected. 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 lengthening member 113. The second bracket portion 1122 is provided with a plurality of first mounting holes X5, and the distances from each of the first mounting holes X5 to the first bracket portion 1121 are different. The first lengthening member 113 is provided with a plurality of second mounting holes X6. The arrangement directions of the plurality of second mounting holes X6 are the same as the arrangement directions of the plurality of first mounting holes X5, and the interval distances between adjacent two second mounting holes X6 are the same as the interval distances between adjacent two first mounting holes X5, so that at least one pair of the first mounting holes X5 and the second mounting holes X6 are oppositely arranged for a fastener 130 to pass through.

[0091] Specifically, the number of the first mounting holes X5 is greater than or equal to two, and specifically may be 2, 3, 4, etc. The first mounting holes X5 may be round holes, square holes, oval holes, etc. The number of the second mounting holes X6 is the same as the number of the 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 can be understood that since the arrangement directions and the interval distances of the first mounting holes X5 and the second mounting holes X6 are the same, at least one pair of the first mounting holes X5 and the second mounting holes X6 can be paired (i.e., oppositely arranged), and then the fastener 130 (such as a rivet, a bolt, etc.) is used to pass through the paired first mounting holes X5 and second mounting holes X6, so that the second bracket portion 1122 and the first lengthening member 113 are connected. During the assembly process, the number of pairs of the first mounting holes X5 and the second mounting holes X6 can be selected along the arrangement direction of the mounting holes, so as to change the size of the first upper frame assembly 110 in the Y-axis direction.

[0092] Taking the number of both the first mounting holes X5 and the second mounting holes X6 being three as an example for illustration. When there are three pairs of the first mounting holes X5 and the second mounting holes X6 forming pairs, the size of the first upper frame assembly 110 in the Y-axis direction is the third height, as shown in Figure 9 and Figure 12 shown. When there are two pairs of the first mounting holes X5 and the second mounting holes X6 forming pairs, the size of the first upper frame assembly 110 in the Y-axis direction is the second height, as shown in Figure 10 and Figure 13 shown. When there is only one pair of the first mounting holes X5 and the second mounting holes X6 forming pairs, the size of the first upper frame assembly 110 in the Y-axis direction is the first height, as shown in Figure 14 shown. Among them, the first height, the second height, and the third height decrease in sequence.

[0093] 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 which are bent and connected. Wherein, 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 extension member 113. The second bracket portion 1122 is provided with a plurality of first mounting holes X5, and the distances from each of the first mounting holes X5 to the first bracket portion 1121 are different. The first extension member 113 is provided with a second mounting hole X6, and the second mounting hole X6 is disposed opposite to any one of the first mounting holes X5 for a fastener 130 to pass through, so that the second bracket portion 1122 and the first extension member 113 form a fixed connection.

[0094] Specifically, the number of the first mounting holes X5 is greater than or equal to two, and specifically may be 2, 3, 4, etc. The first mounting holes X5 and the second mounting hole X6 may both be round holes, square holes, oval holes, etc. The second mounting hole X6 can be paired with any one of the first mounting holes X5 (i.e., disposed opposite), and then the fastener 130 (such as a rivet, a bolt, etc.) is used to pass through the paired first mounting hole X5 and the second mounting hole X6, so that the second bracket portion 1122 and the first extension member 113 are connected. It can be understood that since the distances from each of the first mounting holes X5 to the first bracket portion 1121 are different, therefore, when the second mounting hole X6 is paired with different first mounting holes X5, the distance from the first extension member 113 to the first bracket portion 1121 is different, that is, the height dimension of the first upper frame assembly 110 in the Y-axis direction is different. When the second mounting hole X6 is paired with the first mounting hole X5 close to 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 is paired with the first mounting hole X5 far from the first bracket portion 1121, the dimension of the first upper frame assembly 110 in the Y-axis direction increases, as Figures 16 to 18 shown.

[0095] Please refer to Figures 19 to 22, 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. Among them, 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 extension member 113. The second bracket portion 1122 is provided with a first mounting hole X5. The first extension member 113 is provided with a plurality of second mounting holes X6, and the distances from each of the second mounting holes X6 to the first bracket portion 1121 are all different. The first mounting hole X5 is disposed opposite to any one of the second mounting holes X6 for a fastener 130 to pass through, so that the second bracket portion 1122 and the first extension member 113 form a fixed connection.

[0096] Specifically, the number of the second mounting holes X6 is greater than or equal to two, and specifically can be 2, 3, 4, etc. The first mounting hole X5 and the second mounting holes X6 can both be round holes, square holes, oval holes, etc. The first mounting hole X5 can be paired with any one of the second mounting holes X6 (i.e., disposed opposite), and then the fastener 130 (such as a rivet, a bolt, etc.) is used to pass through the paired first mounting hole X5 and second mounting hole X6, so that the second bracket portion 1122 and the first extension member 113 form a connection. It can be understood that since the distances from each of the second mounting holes X6 to the first bracket portion 1121 are different, when the first mounting hole X5 is paired with different second mounting holes X6, the distance from the first extension member 113 to the first bracket portion 1121 is different, that is, the height dimension of the first upper frame assembly 110 in the Y-axis direction is different. When the first mounting hole X5 is paired with the second mounting hole X6 close to 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 is paired with the second mounting hole X6 far from the first bracket portion 1121, the dimension of the first upper frame assembly 110 in the Y-axis direction increases, as Figures 20 to 22 .

[0097] Regarding the specific details of the relevant structure for realizing height adjustment in the second upper frame assembly 120, the same structure as that of the first upper frame assembly 110 can be adopted. Specifically, reference can be made to the drawings and corresponding descriptions in the foregoing embodiments of the first upper frame assembly 110, and details will not be described herein again. It can be understood that by the combined adjustment of 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.

[0098] Please refer to Figure 23, the 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 by the first hinge assembly 30. The second upper frame assembly 120 and the second lower frame assembly 220 are hinged by the second hinge assembly 40. Specifically, the first lower bracket 212 and the first upper extension piece 113 are hinged by the first hinge assembly 30. The second lower bracket 222 and the second upper extension piece 123 are hinged by the second hinge assembly 40.

[0099] Optionally, the first hinge assembly 30 includes a first hinge pin 310, a first brass gasket 320, a first stainless steel gasket 330, and a first wave washer 340. The first brass gasket 320, the first upper extension piece 113, the first stainless steel gasket 330, the first lower bracket 212, and the first wave washer 340 are arranged in sequence, and the first hinge pin 310 passes through a brass gasket, the first upper extension piece 113, the first stainless steel gasket 330, the first lower bracket 212, and the first wave washer 340, so that the first lower bracket 212 and the first upper extension piece 113 are hinged together.

[0100] Optionally, the second hinge assembly 40 includes a second hinge pin, a second brass gasket, a second stainless steel gasket, and a second wave washer. The second brass gasket, the second upper extension piece 123, the second stainless steel gasket, the second lower bracket 222, and the second wave washer are arranged in sequence, and the second hinge pin passes through a brass gasket, the second upper extension piece 123, the second stainless steel gasket, the second lower bracket 222, and the second wave washer, so that the second lower bracket 222 and the second upper extension piece 123 are hinged together.

[0101] In the first hinge assembly 30, the first brass gasket 320 is relatively soft in texture, which is used to reduce the frictional abnormal noise during the rotation of the first upper extension piece 113 relative to the first lower bracket 212. The first stainless steel gasket 330 is used to improve wear resistance and durability. The first wave washer 340 is used to provide axial pre-tightening force, so that the first upper extension piece 113 can hover at any position during the rotation relative to the first lower bracket 212. The second hinge assembly 40 is the same in principle and will not be elaborated here.

[0102] Please refer to Figure 23, the first lower support 212 includes a first sub - part 2121, a second sub - part 2122, and a third sub - part 2123 that are sequentially bent and connected. Among them, the first sub - part 2121 is connected to the first lower connecting member 211, the second sub - part 2122 is hinged to the first upper extension 113, and the third sub - part 2123 is arranged on the rotation path of the first upper frame assembly 110. The first lower frame assembly 210 may further include a first buffer pad 213. The first buffer pad 213 is provided on the third sub - part 2123, and the first buffer pad 213 may be rubber with a certain elasticity. When the first upper frame assembly 110 impacts the first buffer pad 213 during rotation, the first buffer pad 213 can play an energy - absorbing role, thereby reducing the impact noise.

[0103] Please refer to Figure 23 , the second lower frame assembly 220 may further include a second buffer pad 223. The second buffer pad 223 is provided on the first lower support 212 and is located on the rotation path of the second upper frame assembly 120. The second buffer pad 223 may be rubber with a certain elasticity. When the second upper frame assembly 120 impacts the second buffer pad 223 during rotation, the second buffer pad 223 can play an energy - absorbing role, thereby reducing the impact noise.

Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above - mentioned embodiments within the scope of the present invention, and these improvements and refinements are also regarded as the protection scope of the present invention.
