Description

Technical Field

[0001] This invention belongs to the field of launch box opening mechanism, and more specifically, relates to a fully automatic unlocking and opening mechanism. Background Technology

[0002] As a crucial component of the launch container, the cover must automatically open and reach a predetermined angle during launch, and automatically close and lock after launch, ensuring the entire cover and opening mechanism are reusable. In addition to these functions, considering the limited internal space of the launch container, it is also necessary to design the dimensions of the unlocking and opening mechanism according to the overall spatial layout of the launch container, thereby making the entire launch container structure as compact as possible.

[0003] Patent searches revealed that existing mechanical opening mechanisms are typically located outside the launch box cover. These external parts are prone to wear and tear and impacts due to long-term exposure, which reduces the reliability of the mechanism. Furthermore, existing products cannot meet the design requirements of no protrusions or other defects on the outside of the box, and the drive device of the opening mechanism occupies too much space, failing to meet the requirement of a small space occupancy rate for the launch box.

[0004] Accordingly, there is an urgent need for further improvements in this area to better meet the requirements of fully automatic unlocking and opening of the launch box under various complex operating conditions. Summary of the Invention

[0005] In view of the above-mentioned defects or needs of the existing technology, the purpose of the present invention is to provide a fully automatic unlocking and opening mechanism. By fully combining the operating characteristics and needs of the launch box under various complex working conditions, the opening mechanism is built into the launch box, and targeted improvements are made to its structure and specific settings.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Figure 1 This is a schematic diagram of the overall structure of the fully automatic unlocking and opening mechanism according to the present invention. Figure 1As shown, the lid-opening mechanism according to the present invention mainly includes components such as an upper sliding rod unit 1, a lower sliding rod unit 2, a first crank unit 3, a second crank unit 4, a hinge unit 5, a connecting unit 6, a fixing unit 7, and a driving unit 8. The entire lid-opening transmission mechanism is driven by a motor. The motor is controlled to rotate forward by a switch, and the crank-connecting rod mechanism is driven by an electric push rod, thereby causing the upper and lower sliding rods in the crank-slider mechanism to retract and complete the automatic lid opening. At the same time, by controlling the motor to rotate in reverse, the automatic lid-closing and locking function can be completed.

[0036] This lid-opening mechanism is compact, safe, reliable, easy to maintain, and reusable. The following will provide a detailed explanation with reference to the accompanying drawings.

[0037] The upper sliding rod unit 1 includes a round rod support 101, a round sliding rod 102, a first square sliding rod 103, an upper support 105, a lock head 108, and a stop frame 110. The round rod support 101 and the upper support 105 are respectively fixed to the inside of the launch box cover, and the first square sliding rod 103 and the round sliding rod 102 are sequentially installed between them. The first square sliding rod 103 and the round sliding rod 102 are axially connected to each other and their overall length is adjustable. The stop frame 110 is fixedly mounted on the upper support 105 and is used to restrict the movement of the first square sliding rod 103. The lock head 108 is mounted on the stop frame 110 and is used to lock and unlock the launch box cover.

[0038] More specifically, see also Figure 2 The upper sliding rod unit 1 may also include components such as a nut 104, a torsion spring 106, a square pin 107, a bearing 109, and a round pin 111. The lock head 108 and the stop frame 110 can be fixed by welding, for example, with the torsion spring 106 installed between the stop frame 110 and the round pin 111. The overall structure is mounted on the upper support seat 105 using the round pin 111, causing the stop frame 110 to be in a clockwise rotating trend (the tail end of the stop frame is constrained by the upper support block, and the stop frame can move counterclockwise under force). Furthermore, the round rod support seat 101 and the upper support seat 105 can be fixed to the cover by screws, for example, with the bearing 109 mounted on the first square sliding rod 103 using a square pin 107. The threaded rod at the front end of the round sliding rod 102 can be fitted with a nut 104 and connected to the threaded hole at the rear end of the first square sliding rod 103, thereby facilitating adjustment of the entire sliding rod's length. After adjustment, the slide bar can be tightened with nuts to pass through the round rod support 101 and the upper support 105, thereby ensuring smooth movement of the slide bar.

[0039] See also Figure 4The first crank unit 3 is composed of a first connecting plate 301, a first crank plate 302, and a second connecting plate 303 connected end to end, and they are connected by pivots 304 and 305. The first connecting plate 301 is connected to and linked with the slide rod 102 of the upper slide rod unit 1; the two ends of the first crank plate 302 are pivotally connected to the first connecting plate 301 and the second connecting plate 303, respectively; and the second connecting plate 303 is connected to and linked with the lower slide rod unit 2.

[0040] See also Figure 3 The sliding rod unit 2 includes a lower support 201 and a second sliding rod 202. The lower support 201 is used to install the entire sliding rod unit 2 inside the cover of the launch box. The second sliding rod 202 is connected to the second connecting plate 303 of the first crank unit 3 and maintains linkage.

[0041] More specifically, the 109 bearing is mounted on the second square slide bar 202 using square pin 107, and then mounted as a whole on the lower support seat 201.

[0042] See also Figure 5 The second crank unit 4 is composed of a first rib plate 401, a second rib plate 402, and a second crank plate 403 connected end to end, and they are connected by rotating shafts 404 and 405. The first rib plate 401 is connected to the adapter unit 6 and maintains linkage; the two ends of the second rib plate 402 are respectively connected to the first rib plate 401 and the second crank plate 403 by rotating shafts; the second crank plate 403 is connected to the drive unit 8 and maintains linkage, while also maintaining connection with the fixing unit 7.

[0043] See also Figure 6 The first link 501 and the second link 502 in the hinge unit 5 are connected to the cover support 601 of the transfer unit 6, and its third link 503 and the fourth link 504 are connected to the support base 702 of the fixing unit 7, and are used to control the movement trajectory of the launch box during the flipping of the box cover.

[0044] More specifically, the hinge unit 5 includes a plurality of interconnected links 501, 502, 503 and 504, which are connected by a pivot 505.

[0045] See also Figure 7The adapter unit 6 includes a cover support 601, a drive shaft 602, and a stop block 603. The cover support 601 is used to install the entire adapter unit 6 inside the cover of the launch box. The drive shaft 602 is used to connect the first crank plate 302 of the first crank unit 3 to the first stiffening plate 401 of the second crank unit 4, and realizes the linkage between the two crank plates through its own rotation. The stop block 603 is used to restrict the movement of the first stiffening plate 401 of the second crank unit 4.

[0046] More specifically, the stop block 603 is fixed to the cover support 601 by welding, for example. The drive shaft 602 connects the first crank plate 302 to the first stiffening plate 401 and is fixed to the cover support 601 by nuts and washers. The first connecting plate 301 in the first crank unit is connected to the round slide rod 102 and the second square slide rod 202 by square screws, for example, to ensure smooth movement.

[0047] See also Figure 8 The fixing unit 7 includes an embedded plate 701, a support base 702, and a locking pillow 703. The embedded plate 701 is used to install the entire fixing unit 7 inside the launch box, and the support base 702 is pivotally connected to the second crank plate 403 of the second crank unit 4. In addition, the locking pillow 703 is used to block the first sliding rod 103 of the upper sliding rod unit 1 and the second sliding rod 202 of the lower sliding rod unit to complete the locking function.

[0048] See also Figure 9 The drive unit 8 includes a fixed embedded plate 801 and an electric push rod 802. The fixed embedded plate 801 is used to fix the entire drive unit 8 inside the launch box. The electric push rod 802 is used to provide power for opening or closing the cover, and its output shaft is connected to the second crank plate 403 of the second crank unit 4 and maintains linkage.

[0049] More specifically, the fixed embedded plate 801 may be welded into the housing, and the drive support 803 may be screwed onto the fixed embedded plate 801. The electric actuator 802 is constrained to the drive support 803 by a cylindrical pin 804 and a retaining ring. In addition, one end of the second crank plate 403 in the second crank unit is connected to the support 702, and the other end is connected to the electric actuator 802.

[0050] Based on the above design, the upper slider unit 1, the lower slider unit 2, and the first crank unit 3 together form a crank-slider mechanism, and the second crank unit 4 and the drive unit 8 together form a crank-connecting rod mechanism. Then, the crank-slider mechanism and the crank-connecting rod mechanism are connected by the adapter unit 6, thereby realizing the completion of two movements (the rotation of the crank-connecting rod and the axial movement of the crank-slider) by one drive action.

[0051] In addition, hinge unit 5 is mainly used to control the flipping trajectory of the box cover, and fixing unit 7 is fixed to the launch box and connected to the other end of hinge unit 5. The stop in the adapter unit 6 can limit the movement of the first rib in the second crank unit 4 to prevent the rotation angle of the second crank unit from being too large and thus unable to rotate. The bearings in the upper slide rod unit 1 and the lower slide rod unit 2 are designed to reduce friction so as to better extend into the lock pillow.

[0052] The following will combine Figure 10 and Figure 11 This will explain in detail the working process and operating mechanism of the present invention.

[0053] When the lid is opened, the electric push rod pushes the second crank plate of the second crank unit forward, at which point the lid is locked and cannot be flipped. The crank-connecting rod mechanism drives the drive shaft and rotates it, causing the first crank plate in the first crank unit to move, thus unlocking the lid. A torsion spring may be installed on the front of the lock head, which can be used to return the lock head to its original position the instant the lid unlocks. After unlocking, the lid can be flipped outwards. The hinge unit controls the flipping trajectory of the lid, and the electric push rod continues to push the second crank plate of the second crank unit forward, ultimately opening the lid to its final position.

[0054] When the lid is closed, the electric push rod pulls back the second crank plate of the second crank unit of the lid. At this time, the upper slide bar unit of the lid cannot move because the front end of the first slide bar is blocked by the retaining frame, and the drive shaft remains fixed and cannot rotate. At this time, the second slide bar in the lower slide bar unit also cannot move. The lid is closed under the pull of the crank-connecting rod mechanism. When the lid is close to the end, the lock on the upper slide bar unit is knocked open by the lock pillow fixed on the lid frame. The first slide bar in the upper slide bar unit and the entire crank-slider mechanism are released. Under the action of driving force, the first slide bar and the second slide bar extend and lock into the lock pillow, completing the entire lid closing and locking action.

[0055] Furthermore, the upper and lower sliding rods move synchronously with the same stroke. When the lid is locked in place, the upper sliding rod unit, the lower sliding rod unit, and the first crank unit are on the same straight line, that is, at the dead point of the mechanism, to ensure reliable locking of the lid.

[0056] In summary, compared with existing devices, the cover opening mechanism of the present invention can not only smoothly realize the automatic closing and locking functions and unlocking and opening functions, but also has the advantages of compact structure, safety and reliability, easy maintenance, and reusability. Therefore, it is particularly suitable for various complex working conditions of launch box unlocking and opening applications.

[0057] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
