Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive technology, and in particular to a lock controller. Background Technology
[0002] Currently, most automotive glove box locks are equipped with a pair of locking rods, one rod corresponding to one side, ensuring stable and reliable locking on both sides. The pair of locking rods are connected by a lock controller that synchronizes their movement, enabling simultaneous unlocking.
[0003] Existing lock controllers have relatively complex structures, and the inner end of the lock rod needs to swing, resulting in relatively poor guiding stability after long-term use. For example, a novel push-to-unlock controller disclosed in patent CN213510057U includes a controller housing, a pair of unlocking rods, an unlocking press block, and a pair of transmission teeth. The inner end of the unlocking rod is located inside the corresponding side of the controller housing, and the housing has a guide hole for the unlocking rod to pass through. One end of the unlocking press block extends out of the controller housing, and the other end of the unlocking press block is located inside the controller housing. Inside the controller housing, an elastic reset structure for resetting the unlocking press block is provided at the other end of the unlocking press block. A pair of transmission teeth are rotatably located inside the controller housing, and the pair of transmission teeth are located on both sides of the other end of the unlocking press block. The unlocking press block has a meshing side rack structure corresponding to each transmission tooth, and the transmission teeth are movably connected to the inner end of the corresponding unlocking rod. Its structure is relatively complex. Another example is a locking device for an opening and closing component disclosed in patent CN103459740A, where the inner end of the lock rod needs to swing.

[0027] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and through the description of the examples.
[0028] like Figures 1 to 7 As shown, the lock controller includes a base, a pair of locking rods 1, and a linkage rotation structure for synchronous movement of the pair of locking rods. The linkage rotation structure is located between the pair of locking rods. A set of guide elastic clips 301 are respectively provided on both sides of the linkage rotation structure on the base. The locking rods are located in the guide elastic clips and can be moved horizontally. A stroke groove is provided on the bottom of the linkage rotation structure. A protruding rotation limit structure 7 is provided on the base corresponding to the stroke groove. The rotation limit structure is located in the stroke groove.
[0029] The lock controller of this utility model has a reasonable structural design. A pair of lock rods are symmetrically arranged and connected by a lock controller in the middle. The lock rods are guided by the guide elastic clips on the side. The entire movement of the lock rods is a translation. It is stable and reliable after long-term use. Moreover, the structure is simple and the cost is relatively low.
[0030] The base 2 is a flat plate structure with mounting holes; the overall structure of the lock controller does not require a traditional sealed housing structure, resulting in relatively low cost.
[0031] The rotation limit structure 7 is an elastic protrusion on the base. The protrusion end of the base corresponding to the protrusion is hollowed out. The elastic protrusion has a certain amount of elastic deformation. The rotation limit also has a certain amount of elastic buffering, which makes it stable and reliable for long-term use.
[0032] Each of the guide elastic clips includes a pair of vertical clips that are elastically deformable and are positioned opposite each other. The upper inner side of the vertical clips is provided with a limiting inner protrusion. After long-term use, the wear size of the locking rod will decrease slightly, and the elastic deformation of the vertical clips will adjust to adapt, making it stable and reliable for long-term use.
[0033] The base has a guide support 302 at the bottom between a pair of vertical clips to support the locking rod. The guide support is a vertical plate on the base, and the vertical plate has an arc-shaped structure that matches the bottom of the locking rod. The pair of vertical clips and the guide support form a moving guide structure 3. The contact area between the guide structure and the locking rod is relatively small, which reduces the moving resistance of the locking rod.
[0034] like Figures 2 to 5 As shown, this is an example structural scheme of a lock controller;
[0035] The linkage rotation structure is a rotating gear structure 4. A rotating shaft is provided on the base, the gear structure is located on the rotating shaft and a torsion spring 6 is provided accordingly, and the gear structure can rotate relative to the base.
[0036] The gear structure has a hollow interior. The top center of the gear structure has a shaft hole for the shaft to extend out. The top of the shaft has a top limiting structure 5. The torsion spring is located inside the hollow structure of the gear structure, making the structure compact.
[0037] The inner side of the locking bar is provided with a rack 101 that meshes with the gear 401. Furthermore, the inner side of the locking bar is provided with an inwardly extending inner plate, the rack structure is located below the inner plate, the gear structure is provided with a positioning tooth 402, and the inner plate is provided with an installation positioning notch 102 that mates with the positioning tooth, so as to facilitate alignment during installation.
[0038] like Figure 6 and Figure 7 As shown, this is another example of the lock controller's structural design:
[0039] The linkage rotation structure is a rotating disk 8, which has a pair of opposite extended ends. A rotating shaft is provided on the base, and the rotating disk is placed on the rotating shaft with a corresponding torsion spring. A pin is provided on the extended end, and a linkage hole 103 is provided on the locking rod. The pin is located in the linkage hole, and the lateral dimension of the linkage hole is larger than the longitudinal dimension of the linkage hole, thereby realizing the synchronous movement of a pair of locking rods.
[0040] The rotating disk has a convex cylinder with an opening at the bottom at the center, and a torsion spring is set in the inner cavity of the convex cylinder, which is compact in structure; the top of the convex cylinder has a shaft hole, and the rotating shaft extends out from the shaft hole, and the top of the rotating shaft has a top limiting structure; furthermore, the top of the convex cylinder has a groove, and the top limiting structure is located in the groove 403, which is compact in structure.
[0041] The above description is only a preferred embodiment of the present utility model. The above technical features can be arbitrarily combined to form multiple embodiments of the present utility model.
[0042] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the concept and technical solution of the present invention, or the direct application of the concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
