Referring to fig. 1-2, an embodiment of the present application provides an armrest box for an automobile, including a box body 1, a cover body 2, and two locking mechanisms 3, where the front and rear ends of the cover body 2 are connected to the box body 1 through one locking mechanism 3; when the locking mechanism 3 at the front end or the rear end of the cover body 2 is unlocked, the front end or the rear end of the cover body 2 can be turned upwards and opened correspondingly. That is, when the locking mechanism 3 at the front end of the cover 2 is unlocked, the front end of the cover 2 can be turned upwards to open, so that the front passenger can access the articles; when the locking mechanism 3 at the rear end of the cover body 2 is unlocked, the rear end of the cover body 2 can be turned upwards to be opened, so that a rear passenger can access the articles.

Referring to fig. 3-4, the locking mechanism 3 includes an upper mounting bracket 31, two lower mounting brackets 32, and two mounting shafts 33; the upper mounting frame 31 is arranged on the cover body 2, and the left end and the right end of the upper mounting frame 31 are coaxially provided with shaft holes 311; the two lower mounting brackets 32 are arranged on the box body 1 at left and right intervals, and the two lower mounting brackets 32 are distributed on the left and right sides of the upper mounting bracket 31; the two mounting shafts 33 are respectively connected to the two lower mounting frames 32 in a left-right sliding manner; when the two mounting shafts 33 slide toward each other until the two mounting shafts 33 are inserted into the two shaft holes 311, the cover 2 can rotate around the mounting shafts 33; when the two mounting shafts 33 slide back to each other until the two mounting shafts 33 are disengaged from the two shaft holes 311, the cover 2 is separated from the case 1. That is, when the two mounting shafts 33 at the front end of the cover 2 and the two mounting shafts 33 at the rear end of the cover 2 are inserted into the corresponding shaft holes 311, the front and rear ends of the cover 2 are locked to the case 1, and at this time, the cover 2 is in a locked state; when a front passenger needs to store and take articles, the front passenger only needs to control the two mounting shafts 33 at the front end of the cover body 2 to slide back to the disengaging shaft holes 311 and keep the two mounting shafts 33 at the rear end of the cover body 2 to be respectively inserted into the corresponding shaft holes 311, and at the moment, the cover body 2 can rotate around the two mounting shafts 33 at the rear end of the cover body 2, namely, the front end of the cover body 2 can be turned upwards and opened; when the back row passenger needs to store and take articles, only two mounting shafts 33 at the rear end of the cover body 2 need to be controlled to slide back to the disengaging shaft holes 311, and the two mounting shafts 33 at the front end of the cover body 2 are kept to be inserted into the corresponding shaft holes 311 respectively, at this moment, the cover body 2 can rotate around the two mounting shafts 33 at the front end of the cover body 2, and the rear end of the cover body 2 can be turned upwards to be opened.

Referring to fig. 8-9, in order to ensure that the upper mounting frame 31 can be normally inserted between the two lower mounting frames 32 when the cover body 2 is closed, so as to achieve alignment between the mounting shaft 33 and the shaft hole 311, it is necessary to ensure that the distance L between the lower mounting frame 32 and the upper mounting frame 31 is greater than or equal to 0 mm. In addition, the larger the distance L, the larger the amplitude of the lateral shaking of the lid body 2 with respect to the case body 1. According to the experiment, when the distance L is more than 3mm, the arm leans against the upper end of the cover body 2, and the shaking of the cover body 2 can be obviously sensed, so that the distance L is not more than 3 mm. In summary, in order to ensure the stability of the cover 2 after installation, the distance L is preferably between 0mm and 3 mm.

Referring to fig. 4-5, 7-8, and 10-11, in some embodiments of the present application, the locking mechanism 3 further includes a first driving member 34 for driving the two mounting shafts 33 to slide toward each other. As shown in fig. 5, the first driving member 34 includes two first sliders 341, two first springs 342, and two second springs 343; the two first sliding blocks 341 are respectively connected to the two lower mounting frames 32 in a left-right sliding manner, and the two first sliding blocks 341 are respectively located at the outer sides of the two mounting shafts 33; one end of the first sliding block 341 close to the mounting shaft 33 is connected to the mounting shaft 33 through a first spring 342, and one end of the first sliding block 341 away from the mounting shaft 33 is provided with a first inclined surface 3411; the two second springs 343 are respectively disposed in the two lower mounting frames 32 and force the two first sliding blocks 341 to slide back to back; the cover 2 is provided with a pressing block 221 at a position corresponding to the first inclined surface 3411, when the cover 2 is closed, the pressing block 221 forces the two first sliding blocks 341 to slide in opposite directions through the two first inclined surfaces 3411, so that the two mounting shafts 33 are pushed to slide in opposite directions through the two first springs 342, respectively, until the two mounting shafts 33 are inserted into the two shaft holes 311, respectively. As shown in fig. 11, when the cover 2 is closed, the pressing block 221 presses down on the first inclined surface 3411 to force the first slider 341 to slide toward the mounting shaft 33 (which compresses the second spring 343), so that the mounting shaft 33 can be pushed by the first spring 342 to be inserted into the shaft hole 311. However, during the process of closing the cover 2, i.e., during the period from when the pressing piece 221 starts to contact the first inclined surface 3411 to when the first slider 341 is completely pushed into the lower mounting frame 32, the shaft hole 311 is not initially aligned with the mounting shaft 33, but the shaft hole 311 is aligned with the mounting shaft 33 after the cover 2 is completely closed; therefore, the first spring 342 is connected between the mounting shaft 33 and the first slider 341. When the shaft hole 311 is not aligned with the mounting shaft 33, the lower end of the upper mounting bracket 31 blocks the mounting shaft 33, so that the mounting shaft 33 cannot extend; the pressing block 221 forces the first sliding block 341 to slide toward the mounting shaft 33 through the first inclined surface 3411, and presses the first spring 342 to store energy, after the shaft hole 311 moves to align with the mounting shaft 33, the mounting shaft 33 is forced to be inserted into the shaft hole 311 under the action of the elastic potential energy of the first spring 342, so that the cover body 2 can rotate around the mounting shaft 33. Similarly, when the lock is unlocked, the pressing block 221 limits the first slider 341 from popping out, so when the mounting shaft 33 is controlled to slide toward the first slider 341, the process will press the first spring 342 to store energy, after the mounting shaft 33 is separated from the shaft hole 311, the cover 2 is opened upward until the pressing block 221 is separated from the first inclined surface 3411, under the elastic potential energy of the first spring 342 and the second spring 343, the first slider 341 and the mounting shaft 33 automatically complete the reset, that is, the first inclined surface 3411 on the first slider 341 is completely exposed to the outside of the lower mounting frame 32, and the mounting shaft 33 is completely accommodated in the lower mounting frame 32 (as shown in fig. 4), which is beneficial to protecting the mounting shaft 33 to prevent the mounting shaft 33 from being damaged. In addition, the locking structure avoids the installation of an inclined plane on the installation shaft 33, and ensures the integrity of the installation shaft 33; under the condition of the installation shafts 33 with the same length, the contact area between the outer annular surface of the installation shaft 33 and the inner annular surface of the shaft hole 311 is favorably increased, so that the stability of the rotary connection of the cover body 2 is ensured; when the outer annular surface of the mounting shaft 33 and the inner annular surface of the shaft hole 311 have the same contact area, the length of the mounting shaft 33 can be shortened, and the volume of the entire lock mechanism 3 can be reduced.

Referring to fig. 5 and 11, in some embodiments of the present application, in order to prevent the second spring 343 from completely ejecting the first slider 341, the first slider 341 needs to be limited. For example, the side surfaces of the two first sliders 341 are provided with first bar holes 3412 in the left-right direction; the first driving member 34 further includes two limiting rods 344, one ends of the two limiting rods 344 are respectively fixed to the two lower mounting frames 32, and the other ends of the two limiting rods 344 are respectively connected to the two first strip-shaped holes 3412 in a left-right sliding manner, so as to limit the first sliding block 341 from separating from the lower mounting frames 32. As shown in fig. 11, the first slider 341 can be limited by the sliding fit of the limiting rod 344 and the first strip-shaped hole 3412, and the structure is simple and the installation is convenient.

Referring to fig. 5 and 11, in some embodiments of the present application, a sleeve 3413 protrudes from an end of the first sliding block 341 near the mounting shaft 33, a pin hole 3414 is radially formed through the sleeve 3413, and the pin 345 is connected to the pin hole 3414; one end of the mounting shaft 33 close to the first sliding block 341 is axially slidably connected in the sleeve 3413, and the outer annular surface of the mounting shaft 33 is axially provided with a second strip-shaped hole 331; pin 345 is slidably engaged in second slot 331 from side to limit separation of mounting shaft 33 from sleeve 3413; the first spring 342 is located inside the sleeve 3413 and forces the mounting shaft 33 to slide in a direction away from the first slider 341. This connection reduces the difficulty of assembly between the mounting shaft 33, the first spring 342, and the first slider 341.

Referring to fig. 4 and 6-9, in some embodiments of the present application, the locking mechanism 3 further includes a second actuator 35 for driving the two mounting shafts 33 to slide back to back.
