Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to a press-to-unlock structure for an automotive armrest box. Background Technology

[0002] A car armrest box typically consists of a body and a lid. The lid is hinged to the body, and a locking mechanism is usually provided between the body and the lid. This locking mechanism is mainly used to lock the lid, so that the lid is fastened to the body. The locking mechanism generally includes a movable latch and a button. The lid has a lock hole, and the latch of the locking mechanism engages with the lock hole of the lid to lock it. To unlock, the button needs to be pressed. The button drives the latch to rotate, causing the latch to disengage from the lock hole, thus unlocking the lid.

[0003] A double-door armrest box, also known as a double-opening armrest box, consists of a box body and two lids. The two lids are hinged to the left and right sides of the box body respectively by hinges. The locking mechanism needs to lock and unlock the two lids simultaneously. Therefore, the locking mechanism needs to ensure that the two lids can be locked and unlocked at the same time.

[0004] Existing locking mechanisms, also known as push-to-unlock mechanisms, generally include: a handrail locking mechanism, which includes a latch rotatably mounted on the handrail box for locking the handrail cover; the latch locks and unlocks the handrail cover by rotating forward and backward on the handrail box; and a handrail opening mechanism, which includes an opening button mounting bracket and an opening button slidably connected to the mounting bracket. The bottom of the opening button has a latch push rod extending towards the latch and driving the latch to rotate. The button and latch push rod of this locking mechanism are integrally molded. Because the latch push rod needs to push two latches simultaneously, the machining precision requirements for the latch push rod are high, making production difficult. Furthermore, because the latch push rod and the opening button are perpendicular, their force directions are inconsistent. After prolonged use, the connection between the latch push rod and the opening button is prone to breakage, or the latch push rod may deform, causing the double doors to fail to open synchronously, resulting in a short service life and unstable synchronous opening and closing. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a press-to-unlock structure for an automotive armrest box. This structure can solve the problems of short service life and unstable synchronous opening and closing by improving the internal transmission structure.

[0006] To solve the above-mentioned technical problems, this utility model discloses a press-to-unlock structure for an automotive armrest box, including a button assembly, which includes a button body capable of reciprocating in the height direction; and a locking hook assembly located below the button assembly. The locking hook assembly includes a base, a clutch member, and two locking tongues. The rear end of the clutch member is hinged to the rear end of the base via a first hinge member. The front end of the clutch member has two transmission parts arranged laterally at intervals. The two locking tongues are arranged laterally at intervals on the base, and the bottom end of each locking tongue is hinged to the front end of the base via a second hinge member. The top end of each locking tongue has a hook portion, and the bottom end of each locking tongue extends toward the clutch member with an extension portion. In the assembled state, the bottom end of the transmission part abuts against the corresponding extension portion, and the bottom end of the button body abuts against the top end of each transmission part.

[0007] The button assembly also includes a button base located above the locking hook assembly. The button body is placed in the button base, and a return spring is provided between the button base and the button body to drive the button body to move upward.

[0008] The button body has two pressing parts that are spaced apart in the horizontal direction extending downward from the bottom end. The bottom surface of the button base has a through hole for the pressing parts to pass through, and the pressing parts pass through the through hole and abut against the top end of the corresponding transmission part.

[0009] The pressing part is C-shaped.

[0010] The locking hook assembly also includes a bottom shell, and the base is detachably mounted on the bottom shell by screws.

[0011] The first hinge is a first rotating shaft formed at the rear end of the clutch. The rear end of the base extends upward to form a first hinge seat. The first hinge seat has a hinge hole. The first rotating shaft is inserted into the hinge hole so that the clutch can rotate relative to the base.

[0012] The second hinge is a second rotating shaft formed at the bottom end of the latch. The front end of the base extends upward to form a second hinge seat. The second hinge seat has a hinge groove. The second rotating shaft is placed in the hinge groove so that the latch can rotate relative to the base.

[0013] The locking tongue is designed in a Z-shape.

[0014] The clutch has a movable groove on its side, and a barb extends upward from the bottom of the base. The working end of the barb is inserted into the movable groove from the side of the clutch, and the working end of the barb can move within the movable groove.

[0015] Each lock is equipped with a torsion spring between itself and the base, which drives the bolt to rotate in the upward locking direction.

[0016] Compared with the prior art, the embodiments of this utility model have the following beneficial effects:

[0017] (1) By setting a clutch, the vertical movement of the button body is converted into the rotation of the lock tongue, thereby enabling the button body to drive the lock tongue to unlock. This replaces the previous structure in which the clutch and button body are integrally formed, avoiding the problem of easy breakage, extending the service life of the press-to-unlock structure, and solving the problem of short service life in the past.

[0018] (2) By using a single clutch to drive the two locking tongues to rotate, the synchronicity of the movement of the two locking tongues is ensured, thereby ensuring the working stability of the press-to-unlock structure.

[0019] (3) When in use, the locking hook assembly is fixedly connected to the external armrest box. Since all the components of the locking hook assembly are integrated on the base, if a component fails, the entire locking hook assembly can be removed from the armrest box by removing the base from the armrest box, making subsequent maintenance and repair work more convenient and quick.

[0032] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0033] This utility model discloses a specific embodiment of a press-to-unlock structure for an automotive armrest box. Please see [link / reference]. Figures 1 to 2 The press-to-unlock structure includes a button assembly 1 and a locking hook assembly 2.

[0034] Please see Figures 3 to 4 The button assembly 1 includes a panel 11, a button base 12, and a button body 13, all three located above the locking hook assembly 2. The button base 12 is fixedly mounted to the bottom of the panel 11 by screws. In other embodiments, the button base 12 can also be connected to the panel 11 using a snap-fit ​​structure. The button base 12 has a cylindrical structure. The top surface of the panel 11 has a mounting hole 121. The button body 13 is inserted into the mounting hole 121 and then placed inside the button base 12. Two pressing parts 131, spaced apart in the lateral direction, extend downward from the bottom end of the button body 13. The bottom surface of the button base 12 has a through hole for the pressing parts 131 to pass through, so that the pressing parts 131 protrude from the bottom surface of the button base 12.

[0035] In this embodiment, the button body 13 can reciprocate in the height direction. Specifically, a guide post 132 extends downward from the center of the bottom surface of the button body 13, and a guide hole 122 is provided on the bottom surface of the button seat 12. The guide post 132 is inserted into the guide hole 122, which can play a guiding role so that the button body 13 can move up and down in the button seat 12, thereby realizing the pressing action of the button body 13. In addition, in order to enable the button body 13 to automatically return to its original position, a reset spring 14 is provided between the button seat 12 and the button body 13 to drive the button body 13 to move upward. Optionally, the reset spring 14 is sleeved on the outer peripheral side of the guide post 132, and the reset spring 14 is located in the guide hole 122.

[0036] The button assembly 1 in this embodiment operates as follows: An external force is applied to press the button body 13 downwards, causing the pressing portion 131 of the button body 13 to move downwards through the bottom surface of the button base 12, compressing the return spring 14. Upon returning to its original position, the pressure on the button body 13 is released, and the compressed return spring 14 uses its own elasticity to drive the button body 13 upwards, thereby returning the button body 13 to its original position. It should be noted that a structure can also be provided between the button body 13 and the button base 12 to limit the travel of the button body 13, preventing the button body 13 from dislodging from the button base 12 upon returning to its original position.

[0037] Combination Figures 5 to 6 The locking hook assembly 2 is located below the button assembly 1. The locking hook assembly 2 includes a bottom shell 21, a base 22, a clutch 4, and two locking tongues 3. The bottom shell 21 is part of the armrest box body; see [link to documentation]. Figure 7 The bottom shell 21 has a mounting cavity 210, and the base 22 is detachably installed inside the mounting cavity 210 of the bottom shell 21 by screws. This structure allows for quick assembly and disassembly of the base 22, providing convenience for subsequent maintenance and repair. In other embodiments, the bottom shell 21 and the base 22 can also be detachably connected by a snap-fit ​​structure.

[0038] In this embodiment, the clutch 4 and the two locking tongues 3 are all integrated and mounted on the bottom shell 21. Figure 5 The rear end of the clutch 4 is hinged to the rear end of the base 22 via a first hinge member. Preferably, the first hinge member is a first rotating shaft 42 formed at the rear end of the clutch 4. In this embodiment, a pair of spaced-apart mounting ears 41 extend outwards from the rear end of the clutch 4. Each mounting ear 41 has a first rotating shaft 42 formed on its left and right sides. In other embodiments, the first rotating shaft 42 and the clutch 4 can be separate, i.e., a circular hole is opened in the middle of the mounting ear 41, and the first rotating shaft 42 passes through this hole. Two spaced-apart first hinge seats 221 extend upwards from the rear end of the base 22. See [reference needed]. Figure 7As shown, the first hinge seat 221 has a hinge hole 223 on its side. The first rotating shaft 42 located on one side of the mounting ear 41 is inserted into the hinge hole 223 so that the clutch 4 can rotate relative to the base 22. In order to improve the stability and smoothness of the transmission, the base 22 can also be provided with a hook 52 or a groove 51 to limit the first rotating shaft 42. By using the hook 52 or the groove 51 on the hinge seat 221 to limit the first rotating shaft 42 on the other side of the mounting ear 41, the two ends of the first rotating shaft 42 on both sides of the mounting ear 41 are limited, thereby ensuring the working stability of the clutch 4 and avoiding problems such as lateral deviation of the clutch 4. In addition, by providing the hook 23 and the groove 51, it is easier to assemble the clutch 4. In other embodiments, the number of mounting ears 41 can be set to one, and the number of hinge seats 221 can also be set to one. By opening a through hole arranged in the transverse direction in the hinge seat 221, and opening a notch on the hinge seat 221 for the mounting ears 41 to pass through, during assembly, the mounting ears 41 are placed into the notch. A first rotating shaft 42 with the same length as the hinge seat 221 is inserted into the through hole of the hinge seat 221 and the round hole of the mounting ears 41, which can also enable the clutch 4 to rotate relative to the base 22.

[0039] Combination Figure 8 In this embodiment, to limit the rotation range of the clutch 4, a movable groove 44 is provided on the side of the clutch 4, and a barb 23 extends upward from the bottom surface of the base 22. The working end of the barb 23 is engaged in the movable groove 44 from the side of the clutch 4, and the working end of the barb 23 can move within the movable groove 44. When the clutch 4 is in the locked position, the working end of the barb 23 engages with the groove wall of the movable groove 44, thereby preventing the clutch 4 from rotating too much upward. When the clutch 4 rotates from the locked position to the unlocked position, the working end of the barb 23 moves upward within the movable groove 44 without interfering with the rotation of the clutch 4, thereby ensuring the working stability of the press-to-unlock structure.

[0040] Combination Figure 7 and Figure 8 The clutch block 4 has two transmission parts 43 arranged laterally at its front end. In this embodiment, the transmission parts 43 are C-shaped. The bottom end of each of the two pressing parts 131 of the button body 13 abuts against the top end of a corresponding transmission part 43. The C-shaped structure can better cooperate with the rotation of the clutch 4. Compared with straight or other shaped structures, the C-shape makes unlocking easier and improves the user's operating experience.

[0041] Combination Figure 6 and Figure 9Two latches 3 are horizontally spaced on the base 22, and the bottom end of each latch 3 is hinged to the front end of the base 22 via a second hinge member. Optionally, the second hinge member is a second rotating shaft 32 formed at the bottom end of the latch 3. In this embodiment, the second rotating shaft 32 is formed on both the left and right sides of the latch 3. Three spaced second hinge seats 222 extend upward from the front end of the base 22. Each second hinge seat 222 has a hinge groove 224 at its end facing the other second hinge seat 222. The second rotating shaft 32 is placed in the hinge groove 224 so that the latch 3 can rotate relative to the base 22. It should be noted that the hinge groove 224 can adopt an irregular groove structure, and the end of the second rotating shaft 32 can also adopt an irregular structure. This way, the latch 3 can be disassembled and assembled only when it is rotated to the appropriate angle, which facilitates the assembly of the latch 3 and the limiting of the latch 3.

[0042] Optionally, each latch 3 has a hook 31 at its top end. The hook 31 is mainly used to engage with the lock hole of the outer cover. In this embodiment, the bottom shell 21 is part of the box body, and the bottom shell 21 has corresponding through holes. When locked, the hook 31 of the latch 3 passes through the through hole of the bottom shell 21 and engages with the lock hole of the outer cover. As an optimization, see [reference needed]. Figure 8 and Figure 9 As shown, the bottom end of each latch 3 extends into an extension 33 toward the clutch 4. In the assembled state, the bottom end of the transmission part 43 abuts against the corresponding extension 33, and the bottom end of the button body 13 abuts against the top end of each transmission part 43. When unlocking, the bottom end of the button body 13 pushes against the top end of the transmission part 43, thereby driving the clutch block 4 to rotate. The rotation of the clutch block 4 will drive the bottom end of the transmission part 43 to push against the extension 33 of the latch 3, thereby driving the hook part 31 of the latch 3 to exit the lock hole of the outer cover, thereby achieving unlocking.

[0043] As a preferred embodiment, the locking tongue 3 is arranged in a Z-shape. See also Figure 8 and Figure 9 As shown, a limiting groove 34 is formed on the top surface of the extension 33 of the latch 3, and the bottom end of the transmission part 43 is inserted into the limiting groove 34. This prevents the transmission part 43 from swaying relative to the latch 3, further improving the smoothness of transmission and operational stability. In addition, in order to enable the latch 3 to lock automatically, a torsion spring 6 is provided between each latch 3 and the base 22 to drive the latch 3 to rotate in the locking direction.

[0044] Optionally, to ensure that the latch 3 has sufficient rotation space, the latch 3 is mounted on the base 22, and the extension 33 of the latch 3 is inclined upward. In this embodiment, the bottom surface of the pressing part 131 is flat, which can be understood as the pressing part 131 being rectangular. In other embodiments, the pressing part 131 can also be configured as a frustum, truncated cone, cylinder, or other structures, which can be selectively configured according to actual needs.

[0045] The working process of the press-to-unlock structure in this embodiment is as follows: When unlocking, an external force is applied to press the button body 13 downwards, and the button body 13 moves downwards so that the pressing part 131 of the button body 13 pushes against the top surface of the transmission part 43 of the clutch block. The clutch block rotates due to the push of the button body 13, and the bottom end of the transmission part 43 of the clutch block pushes the extension part 33 of the lock tongue 3 downwards, thereby driving the lock tongue 3 to rotate. The hook part 31 of the lock tongue 3 exits the lock hole of the outer box cover, thereby realizing unlocking.

[0046] The press-to-unlock structure of this embodiment converts the vertical movement of the button body 13 into the rotation of the locking tongue 3 by setting a clutch 4, thereby enabling the button body 13 to drive the locking tongue 3 to unlock. This replaces the previous structure in which the clutch 4 and the button body 13 are integrally formed, avoiding the problem of easy breakage, extending the service life of the press-to-unlock structure, and solving the problem of short service life in the past.

[0047] The press-to-unlock structure of this utility model drives two or more locking tongues 3 to rotate through a single clutch 4, ensuring the synchronicity of the movement of all locking tongues 3, thereby ensuring the working stability of the press-to-unlock structure.

[0048] When in use, the locking hook assembly 2 is fixedly connected to the external armrest box. Since all the components of the locking hook assembly 2 are integrated on the base 22, if a component fails, the entire locking hook assembly 2 can be removed from the armrest box by removing the base 22 from the armrest box, making subsequent maintenance and repair work more convenient and quick.

[0049] Finally, it should be noted that the automobile armrest box press-to-unlock structure disclosed in this utility model embodiment is only a preferred embodiment of this utility model and is only used to illustrate the technical solution of this utility model, not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of this utility model.
