Description

Technical Field

[0001] This utility model relates to a glove box lock structure, and more particularly to a drawer-type glove box lock structure, which enables the opening and closing of the glove box. Background Technology

[0002] In the field of glove box lock structures, existing technologies have proposed various solutions to improve the reliability and synchronization of locking. For example, CN 112252864 B, a glove box lock structure and glove box mechanism, provides an innovative double-sided synchronous locking structure. This patent document discloses a lock body including a mounting base, a transmission gear, a drive linkage, a linkage, and a lock sleeve structure. Its core lies in using a single transmission gear to simultaneously engage the racks on the drive linkage and the linkage, enabling the two linkages to move synchronously in opposite directions during operation. This drives the drive lock head and the linkage lock head at their ends to engage or disengage with the lock sleeves on both sides of the glove box, effectively solving problems such as loosening, abnormal noise, and the risk of secondary opening inherent in traditional lock mechanisms.

[0003] Although glove box lock structures as described in CN 112252864 B have made significant progress in locking reliability and synchronization, their actuation method typically relies on a movable lever on the glove box door, which is often a structure that flips inward around an axis. When the user operates the glove box, they need to pull the lever inward, and this flipping motion inevitably occupies valuable space inside the glove box. To accommodate the flipped lever in the closed state, the inner wall of the glove box door often needs to be designed with a concave structure, or this directly reduces the net depth of the box. This problem is particularly prominent in drawer-type glove boxes where space is already limited, directly reducing the effective storage volume and contradicting the design philosophy of efficient use of automotive interior space.

The inner panel is provided with multiple transverse guide ribs; The right latch is provided with multiple dispersed elastic pressure parts, which press against the outside of the transverse guide rib to ensure stable transverse movement of the right latch. The upper and lower sides of the right latch are respectively provided with multiple openings, and the outer edge of the right latch is bent towards the openings to form the elastic pressure part.

[0009] The preferred technical solution of this utility model to solve the above-mentioned technical problems is as follows: it further includes a handle return spring, which is disposed between the movable handle and the inner panel, and is used to provide a driving force for the movable handle to automatically return to its original position after it is moved by operation.

[0010] The preferred technical solution of this utility model to solve the above-mentioned technical problems is: the back of the movable handle is provided with a limiting rib, and the inner panel is provided with a corresponding limiting block; When the movable handle moves to the unlocked position, the limiting rib abuts against the limiting block to limit its travel and prevent excessive movement. A vertical guide structure is provided between the inner panel and the movable handle to guide the movable handle to move stably.

[0011] The preferred technical solution of this utility model to solve the above-mentioned technical problems is: it further includes a left locking tongue return spring and a right locking tongue return spring; The left latch return spring provides a preload force that keeps the left latch moving toward the lock hole.

[0013] The preferred technical solution of this utility model to solve the above-mentioned technical problems is: the inner panel and the outer panel are further positioned and fixed by a snap-fit ​​structure.

[0014] Another technical solution of this utility model to solve the above-mentioned technical problems is: a vehicle, including a drawer-type glove box lock structure.

[0015] Compared with the prior art, the advantages of this utility model are: it avoids the need for recessed door panels or reduced box depth to accommodate the flip handle, thus maximizing the internal storage volume of the drawer-type glove box, which is in line with the design concept of efficient use of automotive interior space.

[0016] In addition, designers no longer need to reserve internal space for the movement trajectory of the active handle, allowing for more freedom in the internal layout and design of the glove box, thus improving the overall design flexibility.

[0017] Furthermore, the linear sliding motion aligns better with users' intuitive operating habits for drawer-type products, resulting in a more natural and fluid movement. Meanwhile, the movable handle maintains a clean, flush or slightly convex design with the outer panel, enhancing the overall aesthetics of the interior. Attached Figure Description

[0020] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0021] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it will not be further defined and explained in subsequent figures.

[0022] A vehicle includes a drawer-type glove box lock structure 101. (Example) Figures 1 to 3 As shown, this embodiment provides a drawer-type glove box lock structure 101 for use in vehicles. It is installed within the panel assembly 10 of a drawer 103 to enable locking and unlocking of the drawer 103 relative to a drawer-type frame 107. Lock holes 102 are formed on the left and right sides of the drawer-type frame 107 to cooperate with the locking tongue mechanism on the drawer 103.

[0023] Drawer 103 includes an inner panel 11 and an outer panel 12, which are fixedly connected by ultrasonic welding and form a sandwich structure to accommodate the lock structure 20. A snap-fit ​​structure is also provided between the inner panel 11 and the outer panel 12 to assist in positioning and enhance the connection strength, thereby further improving the structural stability of the panel assembly 10.

[0024] like Figures 4 to 9 As shown, the lock structure 20 is located in the interlayer between the inner and outer panels, and mainly includes a movable handle 21, a left locking tongue 22, a right locking tongue 23, a guide mechanism, a reset mechanism, a limit mechanism, and a pressure block assembly.

[0025] The outer panel 12 has a slot 14, through which the movable handle 21 is partially exposed for user pressing. A left connecting post b1 and a right connecting post b2 are fixedly mounted on the back of the movable handle 21, respectively inserted into the left oblique hole b3 of the left latch 22 and the right oblique hole b4 of the right latch 23. The left oblique hole b3 forms a left oblique surface s1, and the right oblique hole b4 forms a right oblique surface s2. When the movable handle 21 moves up and down, the connecting post slides along the oblique surfaces, thereby driving the left and right latches to move horizontally.

[0026] To ensure the stable and reliable movement of the movable handle 21, a left guide hole c1 is provided on the left side of the movable handle 21, and a right guide hole c2 is provided on the right side. Both are oblong holes, and their length direction is consistent with the vertical movement direction of the handle. A left guide post a1 and a right guide post a2 are fixed on the inner panel 11 and are inserted into the corresponding guide holes to limit the movement trajectory of the handle, so that it only moves in a straight line in the vertical direction, avoiding shaking, deviation or jamming.

[0027] A left pressure block 31 and a right pressure block 32 are respectively provided above the left latch 22 and the right latch 23, and both are fixed to the inner panel 11 by screws. The pressure block structure is used to restrict the vertical movement of the latch, thereby ensuring that the latch can only slide in the horizontal direction and improving the stability of the locking action. The inner panel 11 is provided with multiple transverse guide ribs; the right latch 23 is provided with multiple dispersed elastic pressure parts, which press against the outside of the transverse guide ribs to ensure that the right latch 23 moves stably in the lateral direction; multiple openings are provided on the upper and lower sides of the right latch 23, and the outer edge of the right latch 23 bends towards the openings to form elastic pressure parts.

[0028] A handle return spring 40 is arranged between the movable handle 21 and the inner panel 11 to provide an upward return force immediately after the user releases the handle, so that the handle automatically returns to the locked position, improving the ease of use.

[0029] The left latch 22 and the right latch 23 are provided with a continuous preload in the direction of the lock hole by the left latch return spring r1 and the right latch return spring r2, respectively, so that the latches remain naturally extended and enter the lock hole in the non-operational state, thereby achieving automatic locking.

[0030] In addition, a limiting rib v1 is provided on the back of the movable handle 21, and a corresponding limiting block is provided on the inner panel 11. When the movable handle 21 is pressed to its maximum stroke by the user, the limiting rib v1 contacts the limiting block, thereby limiting the handle from moving further down, preventing excessive force on the inclined hole mechanism, and improving the durability of the structure. A vertical guide structure is provided between the inner panel 11 and the movable handle 21 to guide the movable handle 21 to move stably.

[0031] During the assembly of the lock structure 20, the operator first places the left latch 22 and right latch 23 within the guide tracks on the inner panel 11, and then presses them in place using the left pressure block 31 and right pressure block 32, keeping the latches in a horizontal sliding state. Subsequently, pre-compressed latch return springs r1 and r2 are respectively placed between the latches and the inner panel. After the movable handle 21 is inserted into its respective oblique hole through the connecting post, the handle return spring 40 is installed between the handle and the inner panel, forming a complete linkage structure.

[0032] When a user needs to open the glove box drawer 103, they first place their fingers into the slot 14 on the outer panel 12 and press or pull the movable handle 21 in one direction. Under the action of the guide mechanism, the handle moves smoothly vertically, and the connecting pins b1 and b2 slide along the inclined holes on the left and right slopes respectively, pushing the left latch 22 and right latch 23 to move simultaneously away from the lock hole. Once the latches are fully disengaged from the lock hole, the drawer 103 can be pulled out for use.

[0033] After the user releases the handle, the handle return spring 40 quickly pushes the handle back upwards, causing the connecting post to move the latch back towards the keyhole. If the drawer 103 is closed, the latch automatically enters the keyhole under the action of the latch return spring, achieving a self-locking function.

[0034] In summary, through the above structural arrangement, the drawer-type glove box of this embodiment achieves a stable guiding fit between the drawer 103 and the drawer frame 107, while ensuring that the movable handle 21 can reliably trigger and lock during the back-and-forth movement of the drawer 103, eliminating the reliance on the rotation space of traditional flip handles. Utilizing a linear sliding opening method, the front of the glove box does not require a recessed structure to accommodate the flip handle, nor does it need to compress the effective depth of the box, thus fully preserving the internal storage volume and significantly improving the utilization rate of storage space.

[0035] In addition, the movement trajectory of the movable handle 21 is entirely along the front and back direction of the drawer 103. When designers plan the skeleton, ribs or partition structure inside the glove box, they do not need to consider the interference space occupied by the handle flipping, thus obtaining greater freedom of shape and design flexibility.

[0036] Furthermore, the movable buckle 21 and the outer panel 11 can maintain a flush or slightly convex appearance, making the opening part simple and beautiful, in line with the overall visual style of modern automotive interiors. Overall, the structure provided in this embodiment not only optimizes space utilization efficiency but also improves the user's operating experience, enhancing the functionality and aesthetics of the product.
