For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0041] Next, refer to Figures 1 - 7 to describe the locking mechanism 30 according to an embodiment of the present utility model.

[0042] As Figures 1 - 6 shown, for the locking mechanism 30 according to an embodiment of the present utility model, the locking mechanism 30 can be used for an automotive armrest box, and the locking mechanism 30 can also be used in other structures that require locking. This application does not impose any limitations. The present utility model describes the locking mechanism 30 used for an automotive armrest box as an example, but it should not be construed as a limitation to this application.

[0043] The automotive armrest box includes a box body and a box cover. The locking mechanism 30 is installed on the box body, and the box cover is provided with a first lock catch. The locking mechanism 30 includes: a fixed seat 1, a locking member 2, a driving member 3, and a transmission member 4. The locking member 2 is rotatably arranged on the fixed seat 1. The locking member 2 has a second lock catch 221. In the rotation direction of the locking member 2, the second lock catch 221 has a locking position for locking with the first lock catch and an unlocking position for unlocking from the first lock catch. The driving member 3 and the box cover are spaced apart in a first direction. The driving member 3 is used to drive the locking member 2 so that the second lock catch 221 reciprocates between the locking position and the unlocking position. The transmission member 4 is in transmission connection between the locking member 2 and the driving member 3.

[0044] Exemplarily, when the second locking buckle 221 of the locking member 2 is in the locking position, the driving member 3 can drive the transmission member 4 to move. The transmission member 4 can drive the locking member 2 to move. The second locking buckle 221 of the locking member 2 can move from the locking position to the unlocking position. At this time, the first locking buckle and the second locking buckle 221 are separated from each other. At this time, the box cover can be opened, and the user can take and place objects in the box body. After the objects are taken and placed, the box cover can be closed. At this time, the first locking buckle and the second locking buckle 221 are locked to each other again, so that the box cover is locked on the box body.

[0045] In addition, it should be noted that the first direction can refer to the front-back direction shown in the attached Figure 1 figure. The driving member 3 is in front of the box cover and can transmit the acting force to the locking member 2 through the transmission member 4. Thus, the driving member 3 is not likely to interfere with the box cover during assembly, and the assembly difficulty of the driving member 3 and the locking mechanism 30 can be reduced. In addition, when the driving member 3 needs to be triggered to start, by arranging the driving member 3 in front of the box cover and spacing it apart from the box cover by a certain distance, the driving member 3 is easy to be seen and triggered. In addition, when the driving member 3 is triggered and the locking mechanism 30 unlocks the box cover, the opening process of the box cover does not interfere with the continuous triggering process of the driving member 3. Therefore, the locking mechanism 30 of the present invention can also improve the user experience.

[0046] Compared with the locking mechanism 30 for an automotive armrest box in the related art, when the locking mechanism 30 is arranged on the box cover, it is easy to increase the complexity of the box cover. When the locking mechanism 30 is arranged on the box body, in order to ensure aesthetics, the triggering member of the locking mechanism 30 is often hidden under the box cover, which is likely to interfere with the user's hand during the opening process of the box cover, thus affecting the user experience.

[0047] For the locking mechanism 30 of the present application, the driving member 3 is easy to be seen and triggered. In addition, when the driving member 3 is triggered and the locking mechanism 30 unlocks the box cover, the opening process of the box cover does not interfere with the continuous triggering process of the driving member 3. Therefore, the locking mechanism 30 of the present invention can also improve the user experience.

[0048] Furthermore, in the above example, taking the driving member 3 being arranged in front of the box cover as an example, it can be understood that the driving member 3 can also be arranged at other positions. For example, the driving member 3 is arranged on the left side or the right side of the box body. Specifically, the position can be set according to actual needs, and the present application does not make any restrictions.

[0049] Thus, according to the locking structure of the embodiment of the present utility model, by arranging the driving member 3 at an interval from the box cover and being able to transmit the acting force to the locking member 2 through the transmission member 4, the driving member 3 is easy to be seen and triggered. In addition, when the driving member 3 is triggered and the locking mechanism 30 unlocks the box cover, the opening process of the box cover will not interfere with the continuous triggering process of the driving member 3. Therefore, the locking mechanism 30 of the present utility model can also improve the user experience.

[0050] Exemplarily, the driving member 3 can be an electric driving structure or a manual driving button, and the present application does not make any restrictions.

[0051] In some embodiments of the present utility model, as Figures 1 - 6 shown, the locking member 2 is rotatably mounted on the fixed seat 1 through the first rotating shaft 21. In the first direction, the locking member 2 includes a first portion 22 on one radial side of the first rotating shaft 21 and a second portion 23 on the other radial side of the first rotating shaft 21. The second locking buckle 221 is located on the first portion 22, and the transmission member 4 is used to drive the second portion 23 to rotate.

[0052] That is to say, the transmission member 4 can drive the locking member 2 to rotate around the first rotating shaft 21. The locking member 2 has a locking position and an unlocking position in the rotation direction. The locking action and unlocking action of the locking member 2 are simple and efficient. In addition, the locking member 2 of the present utility model can rotate through the first rotating shaft 21, and the structure of the locking member 2 can also be designed according to actual needs. As Figure 4 shown, the locking member 2 includes a hook arm and a hook head. The hook arm includes a first straight arm and a second straight arm that form an included angle with each other. The first rotating shaft 21 is arranged on the first straight arm. The hook head is connected to one end of the second straight arm, and the other end of the second straight arm is connected to the first straight arm. The hook head extends in a direction perpendicular to the second straight arm. Thus, when the locking member 2 rotates, the rotation space of the locking member 2 can be better reduced, which is beneficial to improving the compactness of the locking mechanism 30.

[0053] In some embodiments of the present utility model, as Figures 1 - 6 shown, the transmission member 4 is rotatably mounted on the fixed seat 1 through the second rotating shaft 41. The transmission member 4 includes a third portion 42 on one radial side of the second rotating shaft 41 and a fourth portion 43 on the other radial side of the second rotating shaft 41. The second portion 23 abuts against one side in the rotation direction of the third portion 42, and the driving member 3 abuts against one side in the rotation direction of the fourth portion 43.

[0054] As Figures 1 - 6As shown, the driving member 3 can move downward so that the fourth part 43 rotates downward. At this time, the third part 42 can rotate upward, thereby driving the second part 23 of the locking member 2 to rotate upward, and further causing the first part 22 of the locking member 2 to rotate downward. The second locking buckle 221 on the first part 22 is separated from the first locking buckle of the box cover, thereby unlocking the box cover. The structure is simple and the operation is convenient.

[0055] Exemplarily, a convex portion extending toward the driving member 3 is provided on one side of the fourth part 43 facing the driving member 3. Thus, when the driving member 3 drives the fourth part 43 to rotate, it can better contact the convex portion, thereby better driving the transmission member 4 to rotate.

[0056] In some embodiments of the present invention, as Figures 1 - 6 shown, both the second part 23 and the driving member 3 are located on the same side of the transmission member 4. As Figure 1 and Figure 2 shown in the example, both the driving member 3 and the locking member 2 are provided above the transmission member 4. The second part 23 of the locking member 2 abuts against the upper side of the third part 42 of the transmission member 4, and the driving member 3 abuts against the upper side of the fourth part 43 of the transmission member 4. Thus, the driving member 3 can better drive the locking member 2 to move through the transmission member 4 to lock or unlock the box cover.

[0057] In some embodiments of the present invention, as Figures 1 - 6 shown, the first rotating shaft 21 and the second rotating shaft 41 are parallel and spaced apart along the first direction. Thus, the locking member 2 and the transmission member 4 can be respectively installed on the same fixed seat 1 through two parallel rotating shafts, and the locking member 2 and the transmission member 4 can rotate independently of each other, and the structure is simple, which can enable the locking member 2 and the transmission member 4 to be better linked.

[0058] In some embodiments of the present invention, as Figures 1 - 6 shown, a first elastic member 51 is provided between the locking member 2 and the fixed seat 1. The first elastic member 51 is used to keep the second locking buckle 221 of the locking member 2 in the locking position. The first elastic member 51 includes a first torsion spring provided between the first rotating shaft 21 and the fixed seat 1. That is to say, through the first torsion spring, the second locking buckle 221 of the locking member 2 can be kept in the locking position. When the driving member 3 drives the locking member 2 to rotate through the transmission member 4, the locking member 2 can overcome the elastic force of the first torsion spring, so that the locking member 2 rotates, thereby causing the second locking buckle 221 to move from the locking position to the unlocking position. When the driving member 3 stops driving, the locking member 2 can rotate in the reverse direction under the action of the first torsion spring, thereby causing the second locking buckle 221 to move from the unlocking position to the locking position, and further locking the box cover again.

[0059] In some embodiments of the present invention, as Figures 1 - 6As shown, a second elastic member 52 is arranged between the transmission member 4 and the fixing seat 1 , and the second elastic member 52 includes a spring arranged on the side of the fourth portion 43 away from the driving member 3 . A spring column 53 is arranged on the fixing seat 1 , and the spring is sleeved on the spring column 53 .

[0060] That is to say, when the driving member 3 drives the fourth part 43 to move downward, the fourth part 43 can compress the spring, so that the transmission member 4 can rotate around the second rotating shaft 41, and the rotation of the transmission member 4 can drive the locking member 2 to rotate, so that the locking member 2 unlocks the box cover. When the driving member 3 stops driving, the transmission member 4 can rotate in the opposite direction under the action of the spring. At the same time, the locking member 2 can also rotate in the opposite direction under the action of the first torsion spring, so that the third part 42 of the transmission member 4 and the second part 23 of the locking member 2 are not easy to be misaligned. In addition, by arranging a spring column 53 on the fixing seat 1, when the transmission member 4 rotates downward to a certain angle, the fourth part 43 can abut against the spring column 53, which can prevent the transmission member 4 from rotating excessively, thereby preventing the third part 42 of the transmission member 4 and the second part 23 of the locking member 2 from being misaligned. Moreover, the spring can also deform along the spring column 53 when deforming, and has good stability.

[0061] In some embodiments of the present invention, Figures 1 - 6 As shown, a limiting member 11 is also provided on the fixing seat 1, and the limiting member 11 is used to limit the rotation angle of the transmission member 4. Figure 1 As shown, the limit member 11 includes a limit hook. When the transmission member 4 rotates upward by a certain angle, the limit hook can limit the fourth part 43 of the transmission member 4 from continuing to rotate upward, thereby preventing the transmission member 4 from rotating excessively, and further preventing the third part 42 of the transmission member 4 and the second part 23 of the locking member 2 from being misaligned.

[0062] Exemplarily, a second torsion spring connected to the fixing seat 1 may also be provided on the second rotating shaft 41, and the driving member 3 may be a manual driving button, and a spring may also be provided between the driving member 3 and the box body, which is not limited in the present application.

[0063] In some embodiments of the present invention, Figures 1 - 6 As shown, the second part 23 is provided with a first positioning portion, the third part 42 is provided with a second positioning portion that is positioned and matched with the first positioning portion, the first positioning portion includes a positioning groove 231, and the second positioning portion includes a positioning block 421. Therefore, through the cooperation between the positioning groove 231 and the positioning block 421, the transmission member 4 can stably drive the locking member 2 to rotate when rotating, and can better avoid the transmission member 4 from deviating when rotating to affect the transmission of the locking member 2.

[0064] In some embodiments of the present invention, Figures 1 - 6As shown, the locking mechanism 30 further includes: a mounting base 6, the fixed base 1 is detachably mounted on the mounting base 6, and the mounting base 6 is detachably mounted on the box body.

[0065] Exemplarily, the transmission member 4 and the locking member 2 can be first mounted on the fixed base 1, and then the fixed base 1 is mounted on the mounting base 6, and finally the mounting base 6 is mounted on the box body. In this way, the transmission member 4, the locking member 2, the fixed base 1 and the mounting base 6 can be manufactured independently, which can simplify each structure and make it more convenient and fast to maintain or replace damaged components without disassembling the entire system. Pre-mounting the transmission member 4 and the locking member 2 on the fixed base 1 can reduce the on-site installation workload and help ensure the correct alignment and cooperation between these components. Before finally installing on the box body, the fixed base 1 can be adjusted on the mounting base 6 to ensure that all components are in the best position.

[0066] The present utility model also proposes an automotive armrest box having the locking mechanism 30 of the above embodiment.

[0067] The automotive armrest box according to the embodiment of the present utility model includes a box body, a box cover, and a locking mechanism 30 connected between the box body and the box cover. The end of the box cover facing the driving member 3 has a locking portion, and a first lock catch including a lock groove is provided on the side of the locking portion facing away from the driving member 3. The second lock catch 221 includes a lock hook. That is to say, the mating position of the lock hook and the lock groove is outside the accommodation cavity of the box body. In this way, when taking and placing items, neither the lock hook nor the lock groove is easily touched, which can prevent the user's hand from being scratched by the lock hook or the lock groove.

[0068] In a specific example, the front end of the box cover has a locking portion extending downward, a lock groove is provided on the rear side of the locking portion, the driving member 3 is a manually pressed driving button, the driving member 3 is located in front of the box cover, and the driving member 3 makes the lock hook of the locking member 2 located behind the locking portion through the transmission member 4 and the locking member 2. Thus, it is relatively convenient to lock and unlock the box cover of the automotive armrest box.

[0069] For the automotive armrest box according to the embodiment of the present utility model, by providing the locking mechanism 30 of the above embodiment, the box cover can be unlocked or locked preferably. Moreover, when taking and placing items, neither the lock hook nor the lock groove is easily touched, which can prevent the user's hand from being scratched by the lock hook or the lock groove, and can preferably improve the user experience.
