Abstract
Description
Technical Field
[0001] This utility model belongs to the field of automotive interior technology, and more specifically, it relates to an automotive interior drawer box structure. Background Technology
[0002] Car interiors are various facilities that enhance the driving experience, safety, environmental friendliness, and intelligence. With the rapid development of automobiles, the quality and user experience of car interiors have also improved. Among them, the user experience of car drawers and car refrigerators is also related to the overall vehicle experience. Currently, car drawers are secured to the car panel by the inside of the handle. Moving the handle releases the drawer from the car panel. However, the way the handle is secured to the edge of the car panel, which is relatively thin, makes the car panel not only noisy but also easily damaged by bumps.
[0003] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a new automotive interior drawer structure in order to achieve a more practical purpose. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model provides an automotive interior drawer structure to solve the problem that existing vehicle drawer connection methods, in addition to being noisy, are also prone to damaging the vehicle panel when bumped or knocked.
[0005] The purpose and function of this utility model's automotive interior drawer structure are achieved through the following specific technical means:
[0006] A car interior drawer structure includes a mounting body disposed within a car interior panel. A box body is slidably disposed within the mounting body. A handle is hinged to the front end of the box body. Locking mechanisms are provided between the box body and the mounting body on both sides. The handle is connected to the two locking mechanisms via a linkage. Each locking mechanism includes a locking pin, which is slidably disposed on the box body. Through slots corresponding to the positions of the locking pins are formed on both sides of the box body. Locking slots corresponding to the through slots are formed on both sides of the mounting body. The locking pin can move through the through slots and engage with the locking slots.
[0007] Furthermore, the linkage includes a movable arm and a secondary arm. The box body is provided with multiple slides. The movable arm and the secondary arm are slidably locked in the corresponding slides. The bottom of the movable arm is connected to a locking pin on one side via a slide rod. The box body is provided with a central knob. A gear is sleeved on the central knob. Racks are provided at the bottom of the movable arm and the top of the secondary arm. The gear is located between two sets of racks and meshes with the two sets of racks.
[0008] Furthermore, a slanted notch is provided on one side of the top of the movable arm, and a protrusion is provided on the inner side of the handle, with the end of the protrusion abutting against the surface of the slanted notch.
[0009] Furthermore, a first torsion spring is fitted onto the central torsion spring, with one end of the first torsion spring secured to the gear and the other end secured to the central torsion spring. An inclined surface is provided on the inner side of the locking pin, with the inclined surface facing the mounting body.
[0010] Furthermore, a horizontal shaft is provided through the inner side of the handle, the horizontal shaft is provided through the box body, and a second torsion spring sleeved on the horizontal shaft is engaged between the handle and the box body.
[0011] Furthermore, the end of the box is covered with an outer shell, and an operating port for accommodating a handle is opened in the middle of the outer shell.
[0012] Furthermore, a support shell is provided between the outer shell and the box body. The support shell is installed on the box body. The middle of the support shell is recessed to form an arc-shaped inner cavity. The opening of the arc-shaped inner cavity is connected to the end of the box body. A horizontal shaft is provided through the inner side of the handle. The two ends of the horizontal shaft are provided through the two sides of the recess of the support shell.
[0013] Furthermore, the end edge of the box extends outwards to form a limiting end face.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] The locking pin, which slides at the end of the box, can be moved by the handle to engage or disengage from the locking slots on both sides of the main body, thus completing the opening and closing of the box. This method provides a more stable structure while still using a handle to control the opening and closing of the box. It is convenient to operate, and the sliding unlocking method is quieter and has higher structural strength. Attached Figure Description

[0027] Example:
[0028] As attached Figure 1 To be continued Figure 6 As shown:
[0029] This utility model provides a car interior drawer box structure, including an installation body 1 disposed in the car interior panel, a box body 4 slidably disposed in the installation body 1, and slide rails 401 disposed on both sides of the box body 4, and the box body 4 is slidably locked in the installation body 1 through the slide rails 401.
[0030] The edge of the box body 4 extends outward to form a limiting end face 402, which restricts the position of the box body 4 when it is retracted into the mounting body 1.
[0031] A handle 3 is hinged to the front end of the box body 4. Locking mechanisms are provided between the two sides of the box body 4 and the mounting body 1. The handle 3 is connected to the two locking mechanisms through a linkage. The locking mechanism includes a locking pin 7, which is slidably mounted on the box body 4. Through slots 103 corresponding to the positions of the locking pin 7 are opened on both sides of the box body 4. Locking grooves 12 corresponding to the through slots 103 are opened on both sides of the mounting body 1. The locking pin 7 can move through the through slots 103 and engage in the locking grooves 12. The locking pin 7 engaging in or disengaging from the locking grooves 12 can complete the closing and opening movement of the box body 4. While making the structure more stable, the handle 3 is still used to control the opening and closing of the box body 4. The operation is convenient, and the sliding unlocking method is quieter and has higher structural strength.
[0032] like Figures 2 to 4 As shown, the linkage includes a movable arm 6 and a secondary arm 10. The box body 4 is provided with multiple slides 101. The movable arm 6 and the secondary arm 10 are slidably locked in the corresponding slides 101. The bottom of the movable arm 6 is connected to one side of the locking pin 7 through a slide rod 602. The secondary arm 10 is connected to the other side of the locking pin 7. The box body 4 is provided with a central knob 102. A gear 8 is sleeved on the central knob 102. A rack 9 is provided at the bottom of the movable arm 6 and the top of the secondary arm 10. The gear 8 is located between the two sets of racks 9 and meshes with the two sets of racks 9. When the movable arm 6 moves to one side, the gear 8 drives the secondary arm 10 to move in the other direction, so that the locking pins 7 on both sides can be simultaneously locked into the locking groove 12 or simultaneously released from the locking groove 12.
[0033] Since the top side of the movable arm 6 is provided with a slanted notch 601 and the inner side of the handle 3 is provided with a protrusion 301, the end of the protrusion 301 abuts against the surface of the slanted notch 601. When the handle 3 is moved, the inner protrusion 301 of the hinged handle 3 swings down and the protrusion 301 presses down against the surface of the slanted notch 601, so that the movable arm 6 is pushed to the left. Through the linkage of the gear 8 and rack 9, the locking pins 7 on both sides move inward and move closer to each other. The locking pins 7 leave the locking groove 12, and at this time the box 4 can be pulled out from the mounting body 1.
[0034] like Figure 4 As shown, a horizontal shaft 302 passes through the inner side of the handle 3 and is mounted on the box body 4. A second torsion spring 303 is fitted between the handle 3 and the box body 4 and is sleeved on the horizontal shaft 302. When the box body 4 is closed and the handle 3 is released, the second torsion spring 303 drives the handle 3 to return to its original position. A first torsion spring 11 is fitted on the central torsion 102. One end of the first torsion spring 11 is fitted on the gear 8 and the other end is fitted on the central torsion 102. After the handle 3 returns to its original position, the first torsion spring 11 drives the gear 8 to rotate, and the locking pins 7 on both sides automatically engage in the locking grooves 12.
[0035] The locking pin 7 has an inclined surface on its inner side, facing the mounting body 1. After the operating handle 3 pulls out the box 4, the handle can be released directly to put the locking pin 7 in the reset state. Due to the setting of the first torsion spring 11, the box 4 can be directly pushed into the mounting body 1. During the pushing process, the inclined surface of the locking pin 7 first contacts the mounting body 1, and the locking pin 7 is squeezed and contracted. When the locking pin 7 moves to the locking groove 12, the first torsion spring 11 drives the locking pin 7 to automatically lock into the locking groove 12 to complete the closing of the box 4.
[0036] In this embodiment, the end of the box body 4 is tilted to adapt to the tilt of the car control panel and the operating direction of the user in the vehicle. The tilt of the movable arm 6 allows the movable arm 6 to fit against the end face of the box body 4 and reduces the torque of the handle 3 pushing the movable arm 6 to move. The bottom and middle of the movable arm 6 are provided with slide rods 602, and the bottom slide rod 602 is connected to the locking pin 7.
[0037] Throughout the operation, the end of the box 4 is covered with the outer shell 2, and the middle of the outer shell 2 has an operating port to accommodate the handle 3. The handle 3 is easy to operate, and the sliding noise of the locking pin 7 inside the outer shell 2 is smaller.
[0038] Meanwhile, in order to protect the outer shell 2, a support shell 5 is provided between the outer shell 2 and the box body 4. The support shell 5 is installed on the box body 4. The middle of the support shell 5 is recessed to form an arc-shaped inner cavity. The opening of the arc-shaped inner cavity is connected to the end of the box body 4. A horizontal shaft 302 is provided through the inner side of the handle 3. The two ends of the horizontal shaft 302 are provided through the two sides of the recess of the support shell 5. The setting of the support shell 5 increases the stability of the connection between the handle 3 and the box body 4 and reduces the damage to the outer shell 2 caused by operating the handle 3.
[0039] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
