[0024] Embodiment 1, as Figure 1 - Figure 5As shown, a glove box for preventing accidental opening comprises: a glove box body 1 and a driving unit 3, wherein the driving unit 3 is mounted on the glove box body 1 via a rotating shaft 2 and is used to control the opening of the glove box body 1, wherein the rotating shaft 2 comprises: an inner shaft tube 21, an outer sleeve 22 and an extension shaft 23, wherein both ends of the inner shaft tube 21 are coaxially provided with the extension shaft 23, and the extension shaft 23 is rotatably connected to the glove box body 1, and the outer sleeve 22 is rotatably sleeved on the inner shaft tube 21, and an arc spring sheet 24 is axially provided in the inner shaft tube 21, and the inner shaft tube 21 is provided with a useful A first driving body 25 and a second driving body 26 are used to drive the arc-shaped spring piece 24 to deform. The first driving body 25 and the second driving body 26 are located on both sides of the arc-shaped spring piece 24. One end of the first driving body 25 and the second driving body 26 pass through the inner shaft tube 21 and are respectively placed in the first arc groove 27 and the second arc groove 28 on the outer sleeve 22. A limiting column 29 is installed on the arc-shaped spring piece 24. The limiting column 29 slides in the through hole on the inner shaft tube 21 and cooperates with the limiting groove on the inner wall of the outer sleeve 22 to limit the position.

[0025] Among them, in the initial state, Figure 4 As shown, the first driving body 25 is located in the middle of the first arc-shaped groove 27 , the second driving body 26 is located at the end of the second arc-shaped groove 28 , and the arc-shaped spring piece 24 is in contact with the first driving body 25 .

[0026] This application is normally Figure 4 As shown, when the driving part 3 is moved, the driving part 3 drives the outer sleeve 22 to rotate, and cannot drive the inner shaft tube 21 or the extension shaft 23 to rotate, and thus cannot drive the glove box to open. Only when the outer sleeve 22 rotates to the first driving body 25, the arc spring sheet 24 is driven to deform, and the arc spring sheet 24 moves to the next position by itself, and then drives the limiting column 29 to insert into the limiting groove on the inner wall of the outer sleeve 22, so that the outer sleeve 22 and the inner shaft tube 21 form a whole, thereby realizing driving the glove box to open.

[0027] The present application needs to be reset after the opening is completed. By rotating the outer sleeve 22 counterclockwise, the outer sleeve 22 drives the second driving body 26 to move radially and then drives the arc spring sheet 24 to deform. The arc spring sheet 24 resets itself, and then drives the driving limit column 29 to disengage from the limit groove on the inner wall of the outer sleeve 22, so that the outer sleeve 22 and the inner shaft tube 21 are independent of each other.

[0028] In the second embodiment, the first driving body 25 comprises: a first column 251, a first driving inclined plate 252 for driving the arc spring piece 24 to deform is disposed at the other end of the first column 251, a first limiting ring 253 and a first tension spring 254 are mounted on the first column 251, one end of the first tension spring 254 is connected to the first limiting ring 253, and the other end of the first tension spring 254 is connected to the inner wall of the inner shaft tube 21. The second driving body 26 comprises: a second column 261, a second driving inclined plate 262 for driving the arc spring piece 24 to deform is disposed at the other end of the second column 261, a second limiting ring 263 and a second tension spring 264 are mounted on the second column 261, one end of the second tension spring 264 is connected to the second limiting ring 263, and the other end of the second tension spring 264 is connected to the inner wall of the inner shaft tube 21.

[0029] Among them, one end of the first column 251 and the second column 261 are both spherically processed for easy driving. The inclination angles of the first driving inclined plate 252 and the second driving inclined plate 262 are set according to actual conditions to facilitate driving the arc spring sheet 24 to deform. The fixing method of the two ends of the first tension spring 254 and the second tension spring 264 can be connected by welding or other methods, as long as a fixed connection is achieved.

[0030] The present application can realize the transformation of the two positions of the arc-shaped spring piece 24 by setting the first driving body 25 and the second driving body 26, thereby realizing the switching between on and off, and thus realizing the function of preventing accidental opening.

[0031] In the third embodiment, the arc-shaped spring sheet 24 comprises: a circular base 241 and a spring sheet body 243 . The two circular bases 241 are connected via a connecting rod 242 , and both ends of the spring sheet body 243 are connected to the circular bases 241 via spring bases 244 .

[0033] In the present application, the spring sheet body 243 realizes position change through its own elasticity after being given a certain displacement, thereby driving the movement of the limit column 29. The limit column 29 and the spring sheet body 243 can be fixedly connected or non-contactly connected. When non-contactly connected, the limit column 29 needs to be limited so that it can move in a straight line and have a reset function.

[0034] Embodiment 4 also includes a slide bar mechanism 4 and a transmission plate 5, wherein the slide bar mechanism 4 is slidably arranged on the glove box body 1, and the transmission plate 5 is rotatably installed on the glove box body 1, and the transmission plate 5 is provided with a driving protrusion 6, a transmission protrusion 7 and an elastic connecting part 8, and the transmission protrusion 7 is used to drive the slide bar mechanism 4 to move, and the elastic connecting parts 8 on the two transmission plates 5 are connected by a spring, and the driving part 3 is used to cooperate with a driving arm 9 fixedly arranged on the inner shaft tube 21 or the extension shaft 23.

[0035] In the present application, the driving arm drives the driving protrusion 6 to rotate the transmission plate 5 and then drives the slide bar mechanism 4 to move. The end of the slide bar mechanism 4 is locked with a latch pin.

[0036] In the fifth embodiment, a limit baffle 10 is provided on the glove box body 1, and the limit baffle 10 cooperates with the elastic connection part 8 to limit the position. Such a setting can realize the limitation of the rotation angle of the transmission plate 5. The inner shaft tube 21 is detachably connected to the extension shaft 23, and such a setting is convenient for adapting to the installation environment. The inner shaft tube 21 is formed by two half semicircular pipes connected by bolts, and such a setting is convenient for installing the internal components of the inner shaft tube 21.

[0037] Working process:

[0038] Initial state, such as Figure 4 As shown, when the glove box needs to be opened, the driving part 3 is lifted, thereby driving the outer sleeve 22 to rotate counterclockwise. After rotating to a certain angle, the outer sleeve 22 squeezes the first column 251, and the first column 251 drives the first driving inclined plate 252 to move, pushing the spring sheet body 243 to deform. At the same time, the spring sheet body 243 moves through automatic elasticity, thereby driving the limit column 29 to move. At this time, the end of the limit column 29 contacts the inner wall of the outer sleeve 22. After the driving part 3 is reset by the torsion spring, the end of the limit column 29 is inserted into the groove in the outer sleeve 22, and then the inner shaft tube 21 and the outer sleeve 22 form a whole. At this time, the driving part 3 is lifted again to drive the driving arm 9 to realize the opening and closing of the glove box.

[0039] Reset: By pressing the driving part 3, the outer sleeve 22 is driven to rotate clockwise, and the outer sleeve 22 squeezes the second column 261, and the second column 261 drives the second driving inclined plate 262 to move, pushing the spring sheet body 243 to deform. At the same time, the spring sheet body 243 moves through automatic elasticity, thereby driving the limit column 29 to move, so that the end of the limit column 29 is separated from the groove of the outer sleeve 22, and the inner shaft tube 21 is separated from the outer sleeve 22, and the reset is completed.
