Detailed Description

The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

As shown in fig. 1, an automobile glove box apparatus according to a preferred embodiment of the present invention includes a frame 1, a box body 2, a slide rail mechanism 3, a driving gear 4 and a transmission mechanism 5, wherein the frame 1 is mounted stationary on a vehicle, the box body 2 is drawably installed in the frame 1 through the slide rail mechanism 3 extending in a vehicle traveling direction X, and the driving gear 4 is connected to the box body 2 through 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 cassette body 2, the inner and outer rails 31, 32 cooperating with each other to provide a guide for movement of the cassette body 2 relative to the frame 1.

As shown in fig. 2, the inner rail 31 of the slide rail mechanism 3 is assembled on the frame 1, the driving gear 4, the transmission mechanism 5 and the motor are respectively installed on the frame 1, the outer rail 32 of the slide rail mechanism 3 is assembled on the box body 2 through screws, and then the box body 2 is installed in the frame 1, so that the automobile glove box mechanism is obtained, and the whole automobile glove box mechanism is installed in an automobile.

As shown in fig. 3 to 4, the driving gear 4 is rotatably mounted on the rear side of the frame 1 around the vehicle height direction Z, the transmission mechanism 5 includes a fixedly connected rack 51 and a cam lever 52, the rack 51 is translatably mounted on the frame 1 along the vehicle width direction Y (for example, by a slide rail) and is engaged with the driving gear 4 to translate along with the rotation of the driving gear 4, the box body 2 has a cam groove 21, and a convex point 521 (see fig. 1) of the cam lever 52 is inserted into the cam groove 21 to cooperate with the transmission mechanism 5 to drive the box body 2 to translate along the vehicle traveling direction X, so that the rotation of the driving gear 4 is converted into the translation of the box body 2, and the glove box is opened/closed in a translation manner. Specifically, in the opening process of the glove box, the driving gear 4 pushes the rack 51 to slide, and when the rack 51 slides, the cam lever 52 is driven to slide synchronously, and the cam lever 52 transmits force to the cam groove 21 on the box body 2, so that the box body 2 is opened. In the closing process of the glove box, the box body 2 is slightly pushed, the box body 2 transmits force to the cam driving lever 52 through the cam groove 21, and then the force is transmitted to the rack 51 to drive the driving gear 4 to rotate reversely. After reversing a certain angle, the sensor in the motor senses the motion and sends a signal to the processor, the processor judges through an algorithm, the motor drives the driving gear 4, the rack 51 is pushed to slide again, the cam driving lever 52 is driven to slide again, and then the force is transmitted to the box body 2, so that the box body 2 is electrically closed.

In particular, the cam driver 52 of the transmission mechanism 5 of the present invention is a flat plate structure, which is attached to the bottom of the box body 2 and extends, as shown in fig. 5, the cam driver 52 of the transmission mechanism 5 is in a flat space, which occupies a small storage space of the glove box, so that the glove box mechanism of the present invention has a large storage space.

In particular, the glove box mechanism for the automobile can be in a self-locking state in a closed state, and the box body 2 cannot be opened no matter how much external pushing force or pulling force is applied to the box body 2, so that the characteristic can ensure that the glove box can not be opened by the box body 2 due to the inertia force of collision when the automobile collides at the rear. Specifically, when the glove box is completely closed, the glove box tends to move toward the rear of the vehicle due to the inertial force F (shown in fig. 6) in the event of a rear collision. At this time, as shown in fig. 7, a lateral section 211 of the cam groove 21 extending in the vehicle width direction Y (see fig. 4, perpendicular to the vehicle traveling direction X) functions as a lock. No matter how large the inertia force F is, under the condition that the mechanism is not damaged, the force F is perpendicular to the extending direction of the transverse section 211, force cannot be transferred, the mechanism is locked, and the glove box cannot be opened by the inertia force F. When the motor is driven, the motor drives the rack 51 (see fig. 4) to translate, the salient point 521 of the cam lever 52 moves out of the cross section 211 in the vehicle body width direction Y, and the mechanism is unlocked.

In particular, the glove box mechanism for an automobile of the present invention can close the glove box with a small pushing force in an open state. Specifically, the motor connected to the drive gear 4 has a small cogging torque, the gear box has a small system resistance, and the transmission mechanism 5 can transmit force to the drive gear 4 well. When the box body 2 is opened, if a frontal collision occurs, the passengers and the glove box have a tendency to move toward the vehicle head due to the action of inertia force. At this time, the inclined section 212 of the cam groove 21 (see fig. 4, which is inclined at an angle to the vehicle traveling direction X) is not mechanically self-locked. The glove box is closed under the action of inertia force or the body of a passenger without damaging the mechanism. The parts of the glove box and the like contacting with the passengers meet the requirements of national convex regulations, thereby achieving the purpose of front collision safety.

Returning to fig. 1, left and right stoppers 22 are provided on the rear side of the case 2 to restrict excessive closing of the case 2 and maintain it in a designed closed state. It should be understood that the stop may 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 the box body 2 is closed and prevent abnormal sound.

Returning to fig. 3, the frame 1 has two side stops 11 spaced apart to limit the two extreme positions of the rack 51 to prevent its removal. In addition, the side stop point 11 is provided with an elastic buffer block to avoid the generation of abnormal sound.

It should be understood that the box body 2 of the present invention has a large size, and reinforcing ribs can be additionally arranged as required to reinforce the strength and prevent buckling deformation.

The above embodiments are merely preferred embodiments of the present invention, which are not intended to limit the scope of the present invention, and various changes may be made in the above embodiments of the present invention. All simple and equivalent changes and modifications made according to the claims and the content of the specification of the present application fall within the scope of the claims of the present patent application. The invention has not been described in detail in order to avoid obscuring the invention.
