[0027] like Figure 1 As shown, an armrest box hinge structure includes: an upper hinge bracket 1, a lower hinge bracket 2, a spring 3, and a hinge pin 4. The upper hinge bracket 1 and the armrest box 5 are fixedly connected by an upper positioning structure, which limits the upper hinge bracket 1 and the lower hinge bracket 2 in the X, Y, and Z directions. The lower hinge bracket 2 and the frame 6 are fixedly connected by a lower positioning structure, which limits the lower hinge bracket 2 in the Y and Z directions. The upper hinge bracket 1 and the lower hinge bracket 2 are hinged by the hinge pin 4. The spring 3 is sleeved on the hinge pin 4. Because the upper hinge bracket 1 and the armrest box 5 are limited in the X, Y, and Z directions, and the lower hinge bracket 2 and the frame 6 are limited in the Y and Z directions, the position between the upper hinge bracket 1 and the armrest box 5 can be kept stable. The upper hinge bracket 1 rotates around the hinge pin 4, thereby realizing the opening and closing of the armrest box 5.

[0028] First, assemble the upper hinge bracket 1, lower hinge bracket 2, spring 3, and hinge pin 4 into a hinge structure. Then, assemble the hinge structure with the armrest box 5 and the frame 6 (the frame refers to the car's sub-instrument panel frame). The assembly process is as follows: Specifically, such as Figures 2 to 5 As shown, the upper positioning structure includes a side positioning hole 11 for the upper hinge bracket 1, a front end portion 12 for the upper hinge bracket 1, and a middle positioning hole 13 for the upper hinge bracket 1. The side positioning hole 11 is fixedly connected to the armrest box 5 and limits the upper hinge bracket 1 in the Y direction. The front end portion 12 extends into the armrest box 5 and limits the upper hinge bracket 1 in the Y and Z directions. The middle positioning hole 13 is fixedly connected to the armrest box 5 and limits the upper hinge bracket 1 in the X direction.

[0029] The armrest box 5 includes a lower cover plate 51 and an upper cover plate 52. The side of the lower cover plate 51 has a side positioning boss 511 that mates with the side positioning hole 11, the middle of the lower cover plate 51 has a middle positioning boss 512 that mates with the middle positioning hole 13, and the front end of the lower cover plate 51 has a baffle 513, which forms a limiting space for accommodating the front end portion 12.

[0030] During the assembly of the hinge bracket 1 and the armrest box 5, the front end 12 of the hinge bracket 1 is inserted into the limiting space of the baffle 513, which limits the hinge bracket 1 in the Y and Z directions. Then, the central positioning hole 13 and the central positioning boss 512 are aligned and assembled, and the side positioning hole 11 and the side positioning boss 511 are aligned and assembled. At this time, the central positioning boss 512 limits the hinge bracket 1 in the X direction, and the side positioning boss 511 limits the hinge bracket 1 in the Y direction. The assembly of the hinge bracket 1 and the lower cover plate 51 is now complete, thereby fully limiting the hinge bracket 1 in the X, Y, and Z directions and ensuring the stability of the position of the hinge bracket 1 and the lower cover plate 51.

[0031] Specifically, one end of the rear baffle 53 is snapped into the lower cover plate 51. The rear baffle 53 is attached to the upper hinge bracket 1, and bolts are screwed into the rear baffle 53 to connect it to the lower cover plate 51. The upper hinge bracket 1 also has an upper connecting hole 14, and the lower cover plate 51 has a connecting post 514. The upper end of the connecting post 514 passes through the upper connecting hole 14, and bolts are threadedly connected to the connecting post 514. The connecting hole is located on one side of the side positioning hole 11, and both the connecting hole and the side positioning hole 11 are opened on the side wing of the upper hinge bracket 1.

[0032] When installing the rear baffle 53, first snap the rear baffle 53 into the lower cover plate 51, and then screw a bolt into the other end of the rear baffle 53. After the bolt thread is screwed into the connecting post 514, in the Y direction, the rear baffle 53 and the lower cover plate 51 clamp the upper bracket 1 of the hinge between them, further positioning the upper bracket 1 of the hinge.

[0033] Specifically, the upper cover plate 52 has an assembly hole 521 that mates with the central positioning boss 512. The central positioning boss 512 has a through hole through which a bolt passes, and the bolt connects to the assembly hole 521. After assembling the lower cover plate 51 and the rear baffle 53 with the hinge upper bracket 1, simply place the upper cover plate 52 accordingly, and then screw the bolt into the bottom surface of the lower cover plate 51 to complete the assembly of the upper cover plate 52. At this point, the hinge upper bracket 1 and the armrest box 5 are assembled, and the armrest box 5 and the hinge upper bracket 1 are securely connected in the X, Y, and Z directions, and will not loosen.

[0034] Specifically, the lower positioning structure includes a lower positioning hole 21 for the lower hinge bracket 2, which is fixedly connected to the frame 6 and limits the lower hinge bracket 2 in the Y and Z directions. The frame 6 has a lower positioning post 61 corresponding to the lower positioning hole 21, which passes through the lower positioning hole 21 to fix the lower hinge bracket 2. During the assembly of the lower hinge bracket 2, it is only necessary to align the lower positioning post 61 with the lower positioning hole 21 and then fit them together. The lower positioning post 61 can lock the lower positioning hole 21 in the circumferential direction, realizing the positioning of the lower hinge bracket 2 in the Y and Z directions.

[0035] Specifically, the lower hinge bracket 2 also has a lower connecting hole 22, and the frame 6 has a threaded hole. The bolt passes through the lower connecting hole 22 and is threaded into the threaded hole. After the lower positioning pin 61 and the lower positioning hole 21 are inserted, simply screw the bolt into the lower connecting hole 22 to fasten the lower hinge bracket 2 and the frame 6. At this point, the assembly of the lower hinge bracket 2 is completed.

[0036] The above structure allows for quick assembly of the hinge structure with the armrest box 5 and the frame 6, while ensuring stable opening and closing of the armrest box 5.

[0037] In Embodiment Two, based on Embodiment One, the upper hinge bracket 1 has a limiting side wing 15, and the lower hinge bracket 2 has a limiting baffle 23 corresponding to the limiting side wing 15. The upper hinge bracket 1 rotates relative to the lower hinge bracket 2, causing the limiting baffle 23 to contact the limiting side wing 15. When the armrest box 5 is opened, the upper hinge bracket 1 rotates with the armrest box 5 until the limiting side wing 23 contacts the limiting baffle 15. At this time, the rotation angle of the upper hinge bracket 1 is 90°, which means that the armrest box 5 is in its fully open state.

[0038] An armrest box includes the aforementioned armrest box hinge structure.

[0039] A vehicle including the aforementioned armrest box.

[0040] In summary, the armrest box hinge structure of this utility model ensures a stable connection between the hinge structure and the armrest box by limiting the upper support of the hinge and the lower support of the hinge by the armrest box, thus guaranteeing the connection strength between the two and preventing wobbling during the opening and closing of the armrest box.
