technical field

The invention relates to the technical field of automobile interior parts, in particular to a glove box with a knee impact protection function.

Background technique

Automotive interior parts may have a secondary collision with the human body in the process of car collision, so the safety design of interior parts is very important.

The glove box is located in front of the passenger seat. When the car collides head-on, the occupant will move forward under the action of inertial force. At this time, the lower limbs of the occupant will have a strong collision with the glove box, causing the calf tibia, knee ligament, kneecap and thigh femur. damage to other parts.

SUMMARY OF THE INVENTION

The purpose of the present invention is to address the deficiencies of the above-mentioned technologies, and to provide a glove box with a knee impact protection function. When a vehicle collides, the glove box can follow the occupant's leg contraction and reduce the force on the occupant's leg.

In order to achieve the above purpose, the glove box with knee protection function designed by the present invention includes a box and a box cover, and the box includes a rear box and a front part sleeved and installed on the rear box. a box, the box cover is installed on the front box, the front box is provided with a sleeve part overlapping with the rear box, the sleeve part is provided with an electromagnetic lock, The electromagnetic lock controls the locking or unlocking of the front bucket and the rear bucket.

Preferably, each of the two ends of the sleeve part is provided with one of the electromagnetic locks, and the electromagnetic locks are mounted on the instrument panel beam through the mounting bracket.

Preferably, the electromagnetic lock is provided with a lock tongue, the mounting bracket, the front bucket and the rear bucket are all provided with holes for the lock tongue to pass through, and the lock tongue passes through the holes in sequence. Pass through the mounting bracket, front bucket and rear bucket.

Preferably, the electromagnetic lock is connected with a control device in the vehicle, and after receiving the collision signal, the control device controls the latch of the electromagnetic lock to retract away from the holes of the rear box and the front box.

Preferably, the electromagnetic lock is provided with a spring that resists the lock tongue.

Preferably, the outer diameter of the front box is larger than the outer diameter of the rear box, and the inner wall of the front box is in clearance fit with the outer wall of the rear box.

Compared with the prior art, the present invention has the following advantages:

1. When the vehicle collides, the glove box can follow the occupant's leg contraction, reducing the force on the occupant's leg;

2. The glove box is squeezed by the occupant's legs and the front wall sheet metal of the body, shrinks and deforms and absorbs energy, which not only effectively interrupts the force transmitted from the front wall sheet metal to the occupant's legs, but also weakens the impact of the occupant's legs on the instrument panel. The structure on the glove box, thereby reducing the force on the occupant's legs.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. The indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the indicated device or element must have a specific orientation or a specific orientation. construction and operation, and therefore should not be construed as limiting the invention. Furthermore, the terms "first", "second", and "third" are used for descriptive purposes only and should not be construed to indicate or imply relative importance.

In the description of the present invention, it should be noted that the terms "installed", "connected" and "connected" should be understood in a broad sense, unless otherwise expressly specified and limited, for example, it may be a fixed connection or a detachable connection Connection, or integral connection; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through an intermediate medium, can be internal communication between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood in specific situations.

As shown in FIG. 1 , a glove box with knee protection function includes a box and a box cover 1 , and the box includes a rear box 2 and a front box 3 sleeved and installed on the rear box 2 . , the outer diameter of the front bucket 3 is larger than the outer diameter of the rear bucket 2, the inner wall of the front bucket 3 is in clearance fit with the outer wall of the rear bucket 2, the cover 1 is installed on the front bucket 3, the front The top bucket 3 is provided with a sleeve portion overlapping with the rear bucket 2 , and an electromagnetic lock 4 is arranged on the sleeve portion. The electromagnetic lock 4 controls the front bucket 3 and the rear bucket 2 to be locked or unlocked.

Wherein, as shown in FIG. 2 and FIG. 3 , two ends of the sleeve portion are provided with an electromagnetic lock 4 , and the electromagnetic lock 4 is installed on the instrument panel beam 8 through the installation bracket 5 .

There is a lock tongue 6 on the electromagnetic lock 4, a spring 7 against the lock tongue 6 is arranged in the electromagnetic lock 4, and the mounting bracket 5, the front box 3 and the rear box 2 are all provided with the lock tongue 6 to pass through. Through the hole, the locking tongue 6 passes through the mounting bracket 5, the front bucket 3 and the rear bucket 2 in sequence.

In addition, the electromagnetic lock 4 is connected with a control device in the vehicle. After the control device receives the collision signal, the control device controls the latch 6 of the electromagnetic lock 4 to retract away from the holes of the rear box 2 and the front box 3 .

When this embodiment is used, as shown in Figures 3 and 4, when the vehicle does not collide, the bolt 6 of the electromagnetic lock 4 protrudes and passes through the mounting bracket 5, the front bucket 3 and the rear bucket 2, It plays the role of connecting the mounting bracket 5 , the front bucket 3 and the rear bucket 2 .

When the vehicle collides, as shown in Figures 5 and 6, the control device receives the collision signal to start work, and controls the electromagnetic lock 4 to act. The electromagnetic lock 4 shrinks under the action of electromagnetic force and leaves the rear box 2 and the front The hole of the bucket 3, the connection between the rear bucket 2 and the front bucket 3 and the mounting bracket 5 fails, so that the rear bucket 2 and the front bucket 3 are separated from the mounting bracket 5, and the collision process continues, The front wall sheet metal 9 of the body continues to invade forward, the occupant's legs hit the glove box, and the rear box 2 and front box 3 of the glove box are squeezed by the occupant's legs and the front wall sheet metal 9 of the body, such as As shown in Figure 7, the rear box 2 enters the interior of the front box 3, shrinks and deforms and absorbs energy, which not only effectively interrupts the force transmitted from the front wall sheet metal 9 of the body to the occupant's legs, but also weakens the impact of the occupant's legs. to the structure on the dashboard glove box, thereby reducing the force on the occupant's legs.

The glove box of the present invention has the function of knee impact protection, when the vehicle collides, the glove box can follow the occupant's legs to shrink, reducing the force on the occupant's legs; Extrusion, shrinkage deformation and absorption of energy, which not only effectively interrupts the force transmitted by the front panel sheet metal 9 of the body to the occupant's legs, but also weakens the structure of the occupant's legs hitting the glove box on the dashboard, thereby reducing the occupant's legs. Force.
