[0025] The preferred embodiments of the present invention are given below with reference to the accompanying drawings and described in detail.

[0026] like Figure 1 As shown, a preferred embodiment of the automotive glove box mechanism according to the present invention includes a frame 1, a box body 2, a slide rail mechanism 3, a drive gear 4, and a transmission mechanism 5. The frame 1 is fixedly mounted on the vehicle. The box body 2 is retractably mounted within the frame 1 via the slide rail mechanism 3 extending along the vehicle's travel direction X. The drive gear 4 is connected to the box body 2 via the transmission mechanism 5 to drive the movement of the box body 2 relative to the frame 1, thereby smoothly opening / closing the glove box. In this embodiment, the slide rail mechanism 3 includes left and right inner rails 31 mounted on opposite inner sides of the frame 1 and left and right outer rails 32 mounted on opposite outer sides of the box body 2. The inner and outer rails 31 and 32 cooperate to guide the movement of the box body 2 relative to the frame 1.

[0027] like Figure 2 As shown, the inner rail 31 of the slide rail mechanism 3 is assembled on the frame 1, and the drive gear 4, transmission mechanism 5 and motor are respectively installed on the frame 1. The outer rail 32 of the slide rail mechanism 3 is assembled to the box 2 by screws. Then the box 2 is installed into the frame 1 to obtain the car glove box mechanism. The whole thing can be installed into the car.

[0028] like Figures 3-4 As shown, the drive gear 4 is rotatably mounted on the rear side of the frame 1 about the vehicle height direction Z. The transmission mechanism 5 includes a rack 51 and a cam lever 52 fixedly connected. The rack 51 (e.g., via a slide rail) is translatably mounted on the frame 1 along the vehicle width direction Y and meshes with the drive gear 4 to translate as the drive gear 4 rotates. The housing 2 has a cam groove 21 and a protrusion 521 on the cam lever 52 (see...). Figure 1) is inserted into the cam groove 21 to drive the box 2 to translate along the vehicle travel direction X through the transmission mechanism 5, so as to convert the rotation of the drive gear 4 into the translation of the box 2, and realize the translational opening / closing of the glove box. Specifically, in the opening process of the glove box, the drive gear 4 pushes the rack 51 to slide, and the rack 51 drives the cam lever 52 to slide synchronously, and the cam lever 52 transmits the force to the cam groove 21 on the box 2, so as to make the box 2 open. In the closing process of the glove box, the box 2 is pushed slightly, and the box 2 transmits the force to the cam lever 52 through the cam groove 21, and then transmits the force to the rack 51, and drives the drive gear 4 to reverse. After reversing for a certain angle, the sensor in the motor senses the movement and sends a signal to the processor, and the processor judges through the algorithm, drives the motor, and the motor drives the drive gear 4, and then pushes the rack 51 to slide, and then drives the cam lever 52 to slide, and then transmits the force to the box 2, so as to make the box 2 close electrically.

[0029] Particularly, the cam lever 52 of the transmission mechanism 5 of the present application is a flat plate structure, which is attached to the bottom of the box 2 and extends, as shown in Figure 5 , the cam lever 52 of the transmission mechanism 5 is in a flat space, which occupies a smaller storage space of the glove box, so that the glove box mechanism of the present application has a larger storage space.

[0030] Particularly, the glove box mechanism of the present application can be in a self-locking state in the closed state, no matter how much external pushing or pulling force is applied to the box 2, the box 2 cannot be opened. This feature can ensure that the box 2 will not open the glove box due to the inertial force of the collision when the vehicle is rear-impacted. Specifically, when the glove box is completely closed, if a rear impact occurs, due to the action of the inertial force F (as shown in Figure 6 ), the glove box has a tendency to move towards the tail of the vehicle. At this time, as shown in Figure 7 , the horizontal section 211 (see Figure 4 ) of the cam groove 21 extending along the vehicle width direction Y is perpendicular to the vehicle travel direction X, which plays a locking role. No matter how large the inertial force F is, the force F cannot be transmitted to the horizontal section 211, the mechanism is locked, and the inertial force F cannot open the glove box. When the motor is driven, the motor drives the rack 51 (see Figure 4 ) to translate, and the convex point 521 of the cam lever 52 moves out of the horizontal section 211 along the vehicle width direction Y, and the mechanism is unlocked.

[0031] Particularly, the glove box mechanism of the present application can close the glove box under a smaller return force in the open state. Specifically, the motor connected with the driving gear 4 has a smaller cogging torque, the gear box has a smaller system resistance, and the transmission mechanism 5 can well transmit the force to the driving gear 4. When the box body 2 is opened, if a front collision occurs, the passenger and the glove box have a tendency to move towards the front of the car due to the effect of inertial force. At this time, the inclined section 212 (see Figure 4 , which is at an oblique angle to the direction X in which the car travels) of the cam groove 21 does not self-lock. Under the effect of inertial force, the glove box is closed or closed under the effect of the passenger's body without damaging the mechanism. The parts of the glove box and the like that contact the passenger meet the requirements of the national inward protrusion regulations, thereby achieving the purpose of front collision safety.

[0032] Returning to Figure 1 , the rear side of the box body 2 is provided with a left and right stop block 22, which limits the excessive closing of the box body 2 and keeps it in the designed closed state. It should be understood that the stop block can also be provided on the frame 1. In addition, a buffer block can be added between the frame 1 and the box body 2 to reduce the impact sound when closing the box body 2 and prevent abnormal noise.

[0033] Returning to Figure 3 , the frame 1 has two side stop points 11 arranged at intervals to limit the two extreme positions of the rack 51 and prevent it from coming out. In addition, the side stop points 11 are provided with elastic buffer blocks to avoid the generation of abnormal noise.

[0034] It should be understood that the box body 2 of the present application has a larger size, and can additionally strengthen the strength according to the needs by arranging reinforcing ribs to prevent warping deformation.

[0035] The above description is only a preferred embodiment of the present application and is not intended to limit the scope of the present application. The above-described embodiments of the present application can be variously changed. That is, any simple, equivalent changes and modifications made according to the content of the claims and the description of the present application fall within the scope of the present application. The present application is not described in detail.
