Description

Technical Field

[0001] This invention belongs to the technical field of unlocking structures, specifically relating to a synchronous unlocking structure for a storage box. Background Technology

[0002] In existing automotive dual-sided locking storage boxes, such as glove boxes, the locking and unlocking functions are achieved through rigid connection synchronizers. Their working principle is roughly as follows: When the user presses one of the locking levers, the lever acts rigidly on one end of the synchronizer, causing the synchronizer to slide or rotate. This causes the synchronizer to act on the locking lever on the other side, which in turn causes the locking lever on the other side to move synchronously, disengaging the locking levers on both sides from the locking points on the storage box.

[0003] Because the locking rods and the connecting synchronizer are in rigid contact, the existing unlocking structure experiences significant friction during unlocking, resulting in insufficient smoothness. Furthermore, the locking rods on both sides are actually connected via the central connecting synchronizer, and the rods can only move when the synchronizer is in position. This causes a lag in movement between the left and right locking rods, meaning they do not move synchronously. Moreover, the numerous and bulky connecting structures between the locking rods and the synchronizer on both sides make the existing synchronous unlocking structure complex to maintain and require a large amount of space.

[0004] Therefore, in view of the problems of the existing unlocking structure of double-sided locking storage box, such as the lag in unlocking of the locking rods on both sides, large friction during the movement of the locking rods, and complex structure that occupies space, the present invention discloses a synchronous unlocking structure for the storage box. Summary of the Invention

[0005] This invention discloses a synchronous unlocking structure for a storage box. By replacing the existing rigid connecting synchronizer with a flexible pull rope structure, it saves installation space and can more smoothly and synchronously drive the locking rods on both sides to unlock, making the unlocking process of the storage box smoother and faster.

[0006] This invention is achieved through the following technical solution: A synchronized unlocking structure for a storage box includes a storage box. A left locking rod and a right locking rod are slidably disposed at the left and right ends of the storage box, respectively. A pull rope drive assembly is connected between the left and right locking rods to drive the left and right locking rods to extend and slide synchronously. A locking rod pressing assembly is disposed between the left locking rod and the left end of the storage box or between the right locking rod and the right end of the storage box. The pressing end of the locking rod pressing assembly is inclined and slidably connected to the end of the left or right locking rod.

[0007] Pressing the left or right locking bar using the pressing end of the locking bar pressing assembly causes the left or right locking bar to slide linearly, disengaging it from the lock on the storage box and unlocking it. When one locking bar slides away from the lock, the pull cord drive assembly simultaneously moves the other locking bar away from the lock, thus unlocking both the left and right locking bars at the same time.

[0008] To better realize the present invention, the pull rope drive assembly further includes a pull rope and a pulley. The pulley is rotatably disposed between the left locking rod and the right locking rod. The pull rope is wound around the pulley. One end of the pull rope is engaged with one end of the left locking rod, and the other end of the pull rope is engaged with one end of the right locking rod.

[0009] To better realize the present invention, further, a plurality of pull rope limiting members are provided between the left locking rod and the right locking rod, and the pull rope limiting members are provided with limiting holes, through which the pull rope passes.

[0010] To better realize the present invention, furthermore, both the left and right locking rods are provided with fixed hooks, and the end of the pull rope is provided with a pull rope hook that is connected to the fixed hook.

[0011] To better realize the present invention, furthermore, stabilizing sleeves are provided at both the left and right ends of the storage box, and stabilizing sliding holes are provided on the stabilizing sleeves. The left locking rod and the right locking rod are slidably connected to the stabilizing sliding holes.

[0012] To better realize the present invention, a fixing seat is provided at the right end of the left locking rod and the left end of the right locking rod, and a return spring is provided between the fixing seat and the right end of the left locking rod and between the fixing seat and the left end of the right locking rod.

[0013] To better realize the present invention, the locking rod pressing assembly further includes a pressing block and a pressing seat. The mounting seat is mounted above the left or right locking rod. The pressing block is slidably mounted on the mounting seat in the vertical direction. The bottom of the pressing block is provided with a pressing slope. The end of the left or right locking rod is provided with a pressure-receiving slope that is slidably connected to the pressing slope.

[0014] To better realize the present invention, a vertical reset spring is further provided at the bottom of the pressure block.

[0015] Compared with the prior art, the present invention has the following advantages and beneficial effects: 1. This invention uses a pull rope drive assembly to replace the rigid connection synchronizer in the traditional unlocking structure, which simplifies the unlocking structure, reduces its volume, and reduces the friction during the movement of the lock rods due to the flexible direct connection between the pull rope and the lock rods on both sides. This makes the movement of the entire unlocking structure smoother and ensures that the lock rods on both sides move synchronously, thus solving the problem of lag in the movement of the lock rods on both sides caused by the traditional rigid connection synchronizer. 2. This invention unlocks the device by driving the left and right locking rods on both sides to move synchronously with a flexible pull rope. The pull rope can be flexibly routed according to the structure of the storage box and the surrounding installation structure, making it suitable for installation and use in narrower spaces.

[0018] Example 1: This embodiment presents a storage box synchronous unlocking structure, such as... Figure 1 and Figure 2 As shown, the device includes a storage box 1. A left locking rod 2 and a right locking rod 3 are slidably disposed at the left and right ends of the storage box 1, respectively. A pull rope drive assembly 4 is connected between the left locking rod 2 and the right locking rod 3 to drive the left locking rod 2 and the right locking rod 3 to slide synchronously. A locking rod pressing assembly 5 is disposed between the left locking rod 2 and the left end of the storage box 1 or between the right locking rod 3 and the right end of the storage box 1. The pressing end of the locking rod pressing assembly 5 is inclined and slidably connected to the end of the left locking rod 2 or the right locking rod 3.

[0019] The locking rod pressing assembly 5 is fixedly installed on the storage box 1 with screws. Locking slots are provided at the left and right ends of the door panel of the storage box 1, corresponding to the locking ends of the left locking rod 2 and right locking rod 3, respectively. When the locking ends of the left locking rod 2 and right locking rod 3 are aligned and inserted into the locking slots, the door panel is closed and locked. To open the storage box 1, the left locking rod 2 or right locking rod 3 is tilted and pressed by the pressing end of the locking rod pressing assembly 5, causing the left locking rod 2 or right locking rod 3 to slide away from the locking slots until the locking end of the left locking rod 2 or right locking rod 3 disengages from the locking slots, thus unlocking the door panel, which can then be opened smoothly. When one locking rod slides under pressure, the pull rope drive assembly 4 drives the other locking rod to slide synchronously away from the locking slots, thereby simultaneously unlocking the left locking rod 2 and right locking rod 3.

[0020] The pull-rope drive assembly 4 replaces the rigid connecting synchronizer structure between the left and right locking bars in the traditional unlocking structure. This simplifies the transmission connection between the locking bars, eliminating multiple connecting pairs between the rigid connecting synchronizer and the locking bars, thereby reducing the friction experienced by the locking bars during movement. This allows for smoother and lighter sliding unlocking with less pressing force. Furthermore, the pull-rope drive assembly 4 is directly connected to the left locking bar 2 and the right locking bar 3, without using a rigid connecting synchronizer for intermediate force transmission. Therefore, the pull-rope drive assembly 4 can almost synchronously drive the locking bars on both sides to move synchronously, thus avoiding the movement lag problem caused by the traditional rigid connecting synchronizer.

[0021] Example 2: This embodiment discloses a synchronous unlocking structure for a storage box, which is an improvement on embodiment 1. The pull rope drive assembly 4 includes a pull rope 41 and a pulley 42. The pulley 42 is rotatably disposed between the left locking rod 2 and the right locking rod 3. The pull rope 41 is wound around the pulley 42. One end of the pull rope 41 is engaged with one end of the left locking rod 2, and the other end of the pull rope 41 is engaged with one end of the right locking rod 3.

[0022] At least one pulley 42 is rotatably mounted between the left locking lever 2 and the right locking lever 3 via a pivot, and a pull rope 41 is wound around the pulley 42. Figure 2 For example, when the locking rod pressing component 5 presses the right locking rod 3, causing the right locking rod 3 to slide to the right and disengage from the lock, the second end of the pull rope 41 moves to the right along with the right locking rod 3, and then cooperates with the pulley 42 to cause the first end of the pull rope 41 to drive the left locking rod 2 to slide to the left, thereby realizing the synchronous unlocking of the left locking rod 2 and the right locking rod 3.

[0023] Since the pull rope 41 is a flexible structure, it can be flexibly arranged to avoid additional structures such as air ducts and reinforcing ribs on the storage box 1, effectively saving space. Moreover, compared with traditional rigid connection synchronizers, the arrangement and operation of the pull rope 41 are more convenient and flexible.

[0024] Furthermore, such as Figure 3 As shown, a plurality of pull rope limiting members 43 are provided between the left locking rod 2 and the right locking rod 3. Each pull rope limiting member 43 has a limiting hole, through which the pull rope 41 passes. The pull rope limiting member 43 is installed on the set path by screws or buckles. The pull rope 41 passes through the limiting hole on the pull rope limiting member 43. The limiting hole limits and guides the pull rope 41, ensuring that the pull rope 41 can slide along the preset path, while preventing the pull rope 41 from slipping due to external vibrations or other factors during operation.

[0025] Furthermore, such as Figure 4 As shown, both the left locking rod 2 and the right locking rod 3 are equipped with fixed hooks 44, and the end of the pull rope 41 is equipped with a pull rope hook 45 that is connected to the fixed hooks 44. The pull rope hook 45 is directly connected to the fixed hooks 44, so that the pull rope 41 can drive the left locking rod 2 and the right locking rod 3 to slide and unlock synchronously.

[0026] The rest of this embodiment is the same as that of Embodiment 1, so it will not be described again.

[0027] Example 3: This embodiment discloses a synchronous unlocking structure for a storage box, which is an optimization based on embodiment 1 or 2. Both the left and right ends of the storage box 1 are provided with stabilizing sleeves 6, and the stabilizing sleeves 6 are provided with stabilizing sliding holes. The left locking rod 2 and the right locking rod 3 are slidably connected to the stabilizing sliding holes.

[0028] The stabilizing sleeve 6 is fixedly installed on the storage box 1 with screws. The stabilizing sleeve 6 is equipped with a stabilizing slide, and the stabilizing slide hole can be any of a round hole, square hole, or semi-circular hole. The left locking rod 2 and right locking rod 3 are equipped with guide sections, the outer contour of which corresponds to the shape of the stabilizing slide hole. Through the sliding cooperation between the guide section and the stabilizing slide hole, the left locking rod 2 and right locking rod 3 can slide smoothly along a preset direction, for example, as shown in the example below. Figure 2 Slide the lever in the horizontal direction shown to ensure that the left locking lever 2 and the right locking lever 3 can slide smoothly and synchronously to unlock.

[0029] Furthermore, a fixing seat is provided at the right end of the left locking rod 2 and the left end of the right locking rod 3, and a return spring 7 is provided between the fixing seat and the right end of the left locking rod 2 and between the fixing seat and the left end of the right locking rod 3.

[0030] During the process of unlocking by pressing the left locking lever 2 or the right locking lever 3 away from the lock opening using the locking lever pressing assembly 5, the return spring 7 is stretched. After the pressing force is removed from the locking lever pressing assembly 5, the return spring 7 rebounds and drives the left locking lever 2 and the right locking lever 3 to return to their original positions, ensuring that the left locking lever 2 and the right locking lever 3 automatically return to the locked state where they engage with the lock opening.

[0031] The rest of this embodiment is the same as that of embodiment 1 or 2, so it will not be described again.

[0032] Example 4: This embodiment discloses a synchronous unlocking structure for a storage box, which is an optimization based on any one of embodiments 1-3. The locking rod pressing assembly 5 includes a pressing block and a pressing seat. The mounting seat is straddling the top of the left locking rod 2 or the right locking rod 3. The pressing block is slidably installed on the mounting seat in the vertical direction. The bottom of the pressing block is provided with a pressing slope. The end of the left locking rod 2 or the right locking rod 3 is provided with a pressure-receiving slope that is slidably connected to the pressing slope.

[0033] When the pressing block is set, the pressing slope at the end of the pressing block presses against the pressure slope. Through the inclined sliding fit structure between the pressing slope and the pressure slope, the vertical sliding of the pressing block is converted into the horizontal sliding of the left locking rod 2 or the right locking rod 3, thereby smoothly driving the left locking rod 2 or the right locking rod 3 to slide and unlock.

[0034] Furthermore, a vertical return spring is provided at the bottom of the pressure block. When the pressure block is pressed down, the vertical return spring is compressed and stores elastic potential energy. When the external force pressing the pressure block is removed, the vertical return spring rebounds and drives the pressure block to slide upward and reset.

[0035] Furthermore, the pressing base is provided with a vertical sliding hole, and the pressing block is slidably connected with the vertical sliding hole.

[0036] The rest of this embodiment is the same as any one of embodiments 1-3, so it will not be described again.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.
