Description

Technical Field

[0001] The present invention belongs to the technical field of automotive interior parts. Specifically, the present invention relates to a front storage box of an automotive instrument panel. Background Art

[0002] At present, there are mainly two opening and closing methods for the cover assembly of the front storage box of an automotive instrument panel. The first is the upward-flipping front storage box, and the second is the inward-sliding front storage box. For the upward-flipping front storage box, due to the limitation of the Z-direction space of the automotive instrument panel, the storage cavity can only be set very shallow, and it has gradually been phased out by the market. For the inward-sliding front storage box, the depth of the storage cavity is the Y-direction space of the automotive instrument panel, with a deeper depth and more storage capacity.

[0003] However, for the inward-sliding front storage box, the cover assembly that is opened and closed by pressing will open itself due to the inertia during sudden braking, with obvious functional defects and poor user experience. Summary of the Invention

[0004] The present invention provides a front storage box of an automotive instrument panel to solve the technical problems existing in the above background art.

[0005] To achieve the above object, the technical solution adopted by the present invention is: a front storage box of an automotive instrument panel, including a lower housing, an upper housing, a cover assembly, a support arm assembly, a locking mechanism assembly, and an inertia lock assembly. The slot of the lower housing is inserted into and fastened with the buckle of the upper housing by screws. The cover assembly is connected to the upper housing for opening and closing the cover through the support arm assembly. The locking mechanism assembly for locking the cover assembly is fixedly connected to the right side of the upper housing.

[0012] Preferably, the locking mechanism assembly includes a locking plate, a labyrinth pointer, a first damper, a tension spring, a top plate seat, and a left restraint sliding pin. The locking plate is provided with a right restraint sliding pin and a track pin. The right restraint sliding pin passes through the restraint arc groove and is inserted into the first pin card seat, and is hinged to the first pin card seat;

[0013] The labyrinth pointer is fixedly connected to the locking plate. The labyrinth pointer is provided with a locking pin, and the locking pin slides in a first special-shaped sliding groove and a second special-shaped sliding groove. The locking pin seat is used to lock the locking pin;

[0014] The first damper is clamped to the locking plate. The gear on the first damper meshes with the track arc rack. One end of the tension spring is hooked to the locking plate, and the other end is hooked to the upper housing;

[0015] The top plate seat is fixedly connected to the right side of the upper housing. The top plate seat is provided with a track arc bar, and the track arc groove formed between the track arc bar and the upper end of the track arc rack is used to restrict the movement of the track pin;

[0016] The left restraint sliding pin passes through the restraint arc groove and is inserted into the first pin card seat, and is hinged to the first pin card seat.

[0017] Preferably, the inertia lock assembly includes a swing arm, a third hinge pin shaft, a swing arm torsion spring, and a second damper. The middle part of the swing arm is screwed into the second hinge seat through the third hinge pin shaft so that the swing arm is hinged to the third hinge pin shaft. The swing arm torsion spring is sleeved on the second hinge seat, and the swing arm is subjected to a torsional restoring force. A sector gear is arranged in the middle of the swing arm, and a counterweight is arranged at the lower end of the swing arm. The second damper is fixedly connected to the left side of the upper housing. The gear on the second damper meshes with the sector gear.

[0018] The beneficial effects of adopting the above technical solutions are as follows:

[0019] 1. For the front storage box of the vehicle instrument panel of the present invention, when closing the cover assembly, with the manual pressing of the cover assembly, the cover assembly rotates around the second pin card seat, and the support arm rotates clockwise around the first hinge pin shaft against the elastic restoring force of the support arm torsion spring.

[0020] The pin socket carrier 1 slides along the constraint arc groove with the right constraint sliding pin and the left constraint sliding pin; meanwhile, the right constraint sliding pin drives the locking plate, the track pin, the labyrinth pointer, the locking pin, and the damper 1 to slide along the constraint arc groove together; among them, the track pin moves along the track arc groove formed between the track arc bar and the upper end of the track arc rack, the gear on the damper 1 moves along the track arc rack without damping, the tension spring is further stretched, and the locking pin moves from the special-shaped chute 1 to the groove position on the locking pin seat.

[0021] Then, manually release the force applied to the cover assembly. At this time, under the elastic restoring force of the tension spring, the locking pin falls into the groove on the locking pin seat, realizing the locking of the cover assembly.

[0022] When opening the cover assembly, first manually press the cover assembly, so that the cover assembly rotates further around the pin socket carrier 2, and the pin socket carrier 1 drives the right constraint sliding pin and the left constraint sliding pin to slide further along the constraint arc groove to the end of the constraint arc groove; meanwhile, the right constraint sliding pin drives the locking plate, the track pin, the labyrinth pointer, the locking pin, and the damper 1 to slide along the constraint arc groove together; among them, the track pin moves along the track arc groove formed between the track arc bar and the upper end of the track arc rack, the gear on the damper 1 moves along the track arc rack without damping, the tension spring is stretched further again, and the locking pin moves from the groove position on the locking pin seat to the special-shaped chute 2.

[0023] Then, manually release the force applied to the cover assembly. At this time, under the elastic restoring force of the tension spring, the locking pin slides along the special-shaped chute 2. At this time, under the elastic restoring force of the arm torsion spring, the arm rotates counterclockwise around the hinge pin 1. Under the elastic restoring force of the tension spring, the locking plate drives the track pin, the labyrinth pointer, the damper 1, the right constraint sliding pin, and the left constraint sliding pin to slide along the constraint arc groove together. Among them, the track pin moves along the track arc groove formed between the track arc bar and the upper end of the track arc rack, the gear on the damper 1 moves along the track arc rack with damping, and the pin socket carrier 1 drives the cover assembly to move upward into the upper housing, realizing the damped opening of the cover assembly.

[0024] For the front storage box of the vehicle instrument panel of the present invention, when closing the cover assembly, there is the elastic restoring force of the arm torsion spring and the tension spring. When opening the cover assembly, there is the damping of the damper 1. During closing and opening, there is no noise and the user experience is good.

[0025] 2. For the front storage box of the vehicle instrument panel of the present invention, when the cover assembly is in the closed state, when the vehicle encounters an emergency and brakes suddenly, it can prevent the cover assembly from having a tendency to rotate clockwise and open due to inertia. When the vehicle encounters an emergency and brakes suddenly, at this time, the inertia locking assembly works.

[0026] Under the action of the counterweight, the swing arm rotates clockwise around the hinge pin three to overcome the elastic restoring force of the swing arm torsion spring, so that the upper end of the swing arm moves to contact the rear limit protrusion. During this process, the gear on the damper two has no damping on the sector gear. At this time, the upper end of the swing arm presses against the left restraint sliding pin, preventing the left restraint sliding pin from moving along the restraint arc groove, thus avoiding the opening of the cover assembly due to sudden braking.

[0027] After the inertia of the vehicle during sudden braking disappears, the swing arm rotates counterclockwise under the action of the elastic restoring force of the swing arm torsion spring until the upper end of the swing arm contacts the front limit protrusion. During this process, the gear on the damper two has damping on the sector gear, ensuring the smooth reset of the swing arm.

[0028] For the front storage box of the vehicle instrument panel of the present invention, the cover assembly is prevented from opening due to sudden braking through the inertia lock assembly. Brief Description of the Drawings

[0072] The following uses specific embodiments to elaborate on the specific working mode:

[0073] Embodiment 1:

[0074] For the front storage box of the vehicle instrument panel of the present invention, when closing the cover assembly 3, with the manual pressing of the cover assembly 3, the cover assembly 3 rotates around the pin socket 3-13, and the support arm 4-1 rotates clockwise around the hinge pin 4-2 against the elastic restoring force of the support arm torsion spring 4-3.

[0075] The pin socket base one 3-11 slides along the constraint arc groove 2-3 with the right constraint sliding pin 5-10 and the left constraint sliding pin 5-6; meanwhile, the right constraint sliding pin 5-10 drives the locking plate 5-1, the track pin 5-11, the labyrinth pointer 5-2, the locking pin 5-20, and the damper one 5-3 to slide along the constraint arc groove 2-3 together; among them, the track pin 5-11 moves along the track arc groove formed between the track arc strip 5-50 and the upper end of the track arc rack 2-4, the gear on the damper one 5-3 moves along the track arc rack 2-4 without damping, the tension spring 5-4 is further stretched, and the locking pin 5-20 moves from the special-shaped chute one 2-50 to the groove position on the locking pin seat 2-52.

[0076] Then, manually release the force applied to the cover assembly 3. At this time, under the elastic restoring force of the tension spring 5-4, the locking pin 5-20 falls into the groove on the locking pin seat 2-52, realizing the locking of the cover assembly 3.

[0077] When opening the cover assembly 3, first manually press the cover assembly 3, so that the cover assembly 3 further rotates around the pin socket base two 3-13, and the pin socket base one 3-11 drives the right constraint sliding pin 5-10 and the left constraint sliding pin 5-6 to further slide along the constraint arc groove 2-3 to the end of the constraint arc groove 2-3; meanwhile, the right constraint sliding pin 5-10 drives the locking plate 5-1, the track pin 5-11, the labyrinth pointer 5-2, the locking pin 5-20, and the damper one 5-3 to slide along the constraint arc groove 2-3 together; among them, the track pin 5-11 moves along the track arc groove formed between the track arc strip 5-50 and the upper end of the track arc rack 2-4, the gear on the damper one 5-3 moves along the track arc rack 2-4 without damping, the tension spring 5-4 is stretched further again, and the locking pin 5-20 moves from the groove position on the locking pin seat 2-52 to the special-shaped chute two 2-51.

[0078] Then, manually release the force applied to the cover assembly 3. At this time, under the elastic restoring force of the tension spring 5-4, the locking pin 5-20 slides along the special-shaped chute two 2-51. At this time, under the elastic restoring force of the arm torsion spring 4-3, the arm 4-1 rotates counterclockwise around the hinge pin shaft one 4-2. Under the elastic restoring force of the tension spring 5-4, the locking plate 5-1 drives the track pin 5-11, the labyrinth pointer 5-2, the damper one 5-3, the right constraint sliding pin 5-10, and the left constraint sliding pin 5-6 to slide along the constraint arc groove 2-3 together. Among them, the track pin 5-11 moves along the track arc groove formed between the track arc strip 5-50 and the upper end of the track arc rack 2-4, the gear on the damper one 5-3 moves along the track arc rack 2-4 with damping, and the pin socket base one 3-11 drives the cover assembly 3 to move upward into the upper housing 2, realizing the damped opening of the cover assembly 3.

[0079] The storage box at the front end of the automobile instrument panel of the present invention has the elastic restoring force of the support arm torsion spring 4-3 and the tension spring 5-4 when the cover assembly 3 is closed, and the damper 5-3 has the damping when the cover assembly 3 is opened, so that closing and opening are noiseless and the user experience is good.

[0080] Embodiment 2:

[0081] The storage box at the front end of the automobile instrument panel of the present invention, when the cover assembly 3 is in a closed state, prevents the cover assembly 3 from opening due to the tendency of clockwise rotation due to inertia when the automobile encounters an emergency and brakes suddenly. When the automobile encounters an emergency and brakes suddenly, the inertia lock assembly 6 works.

[0082] Under the action of the counterweight 6-11, the swing arm 6-1 rotates clockwise around the hinge pin shaft three 6-2 to overcome the elastic restoring force of the swing arm torsion spring 6-3, so that the upper end of the swing arm 6-1 moves to contact the rear limit protrusion 2-9. During this process, the gear on the damper two 6-4 has no damping on the fan gear 6-10. At this time, the upper end of the swing arm 6-1 presses the left constraint slide pin 5-6 to prevent the left constraint slide pin 5-6 from moving along the constraint arc groove 2-3, thereby avoiding the cover assembly 3 from opening due to emergency braking.

[0083] After the inertia of the car's emergency brake disappears, the swing arm 6-1 rotates counterclockwise under the elastic restoring force of the swing arm torsion spring 6-3 until the upper end of the swing arm 6-1 contacts the front limit protrusion 2-8. During this process, the gear on the damper 2 6-4 damps the fan gear 6-10, ensuring that the swing arm 6-1 is smoothly reset.

[0084] The storage box at the front end of the automobile instrument panel of the present invention prevents the cover assembly 3 from opening due to emergency braking through the inertial lock assembly 6 .

[0085] The present invention is described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention; or the above-mentioned concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
