Technical Field

[0001] This utility model relates to a lock for a charging cabinet, specifically a push lock for a new energy battery in a charging cabinet. Background Technology

[0002] Shared new energy battery cabinets, also known as shared battery swapping cabinets, are a form of existing charging cabinets. They are centralized, unattended, intelligent cabinet-style devices that store multiple fully charged standardized lithium batteries. Users can scan a QR code via a mobile app or mini-program to retrieve a fully charged battery and return the depleted battery from their vehicle, enabling quick battery replacement and alleviating range anxiety. Simultaneously, they solve the range and charging problems of urban light electric vehicles, making them popular with frequent users such as food delivery and courier services. They are expected to become an important component of new urban infrastructure with huge future development potential. Existing charging cabinets with locking hooks include patent application number 202320518841.6 disclosed in Chinese patent literature, authorized on August 1, 2023, with the utility model name "Reliable Multi-Compartment Battery Swapping Cabinet"; however, these products and similar products rarely use linear motors, relying on the linear motion of the motor to drive the rotation and unlocking of the locking hooks. Summary of the Invention

[0003] To overcome the above shortcomings, the purpose of this utility model is to provide a new energy battery push lock for charging cabinets, thereby solving the technical problem that existing similar products rarely use linear motors and rely on the linear motion of the linear motor to drive the rotation and unlocking of the lock hook. This objective is achieved through the following technical solution.

[0004] A new energy battery push lock for a charging cabinet includes a locking hook inside its housing that unlocks by swinging or locks by impact. The housing comprises a lock shell and a shell cover. Key structural design features symmetrical sliding holes on both sides of the housing to facilitate linear movement of the top plate. The top plate extends from its two ends via guide rods integrated at one end and inserts into the sliding holes on both sides of the housing. A pin hole at the other end of the top plate connects to a pin at the protruding end of a screw rod serving as the driving shaft of a linear motor within the housing. The linear motor is fixedly mounted inside the housing. One end of a guide post inside the housing inserts into or passes through a guide hole on one side of the top plate. The front end of the linear guide hole on the top plate has a bend hole that drives the locking hook inside the housing to rotate. The other end of the guide post is connected to the guide post hole on one side of the middle of the lock hook. The other side of the middle of the lock hook is connected to the screw through the screw hole. The screw is fixed to the housing below the lock hook. A torsion spring is provided at the screw for the lock hook to swing and reset. The hook part of one end of the lock hook under the top plate extends out of the housing and engages with the hook shaft on the side of the battery end shell. When unlocking, the linear motor pushes the top plate forward through the pin shaft. At the same time, the guide hole of the top plate pushes the guide post from the bend position of the guide hole to the straight position and changes direction, causing the lock hook to rotate. The hook part of the lock hook disengages from the hook shaft of the battery end shell. When the battery is placed in the cabinet, it collides with the lock hook through the hook shaft of the battery end shell, and the lock hook swings and resets to engage. The working principle of the above lock hook is similar to the working principle of the latch in the existing latch lock. When locking, the lock hook is driven to rotate by collision to achieve locking. The above and below corresponding holes can also be replaced with slots as needed. The hole and slot designs can be interchanged. The above screws, guide posts, etc. can also be replaced with rivets, pin shafts, pins, etc.

[0005] The top plate is aligned with the outer diameter of one side of the battery end case, and the top plate continues to move forward to push the battery out of the cabinet.

[0006] The housing contains a first micro switch and a second micro switch. When the top plate moves linearly to one end of the sliding hole, it triggers the corresponding first or second micro switch. The linear motor, the first micro switch, and the second micro switch are connected to the circuit board via wiring. Thus, the position of the top plate and the on / off status of the new energy battery push lock are monitored through the first and second micro switches.

[0007] The first and second microswitches are respectively disposed on the inner wall of one side of the sliding hole inside the housing. When the top plate inside the housing moves linearly to one end of the sliding hole, the top plate triggers the corresponding first or second microswitch below or above via the guide rod on that side. The above describes the specific location of the first and second microswitches.

[0008] The housing at the protruding part of the locking hook is provided with a side lug to limit the swing of the locking hook. The aforementioned side lug is formed by stamping a sheet of the housing.

[0009] The other end of the locking hook curves outward and extends through a through-hole on one side of the housing. The other end of the extended locking hook can be fitted with a corresponding touch element or limiting structure as needed.

[0010] The top plate is rectangular, with one end bent by stamping, and the other end formed by stamping a zigzag groove that is connected to the outer diameter key surface of the guide rod by screws. The top plate is formed by stamping sheet metal, which facilitates production.

[0011] This utility model has a reasonable structural design, is easy to assemble and install, simple to monitor, and has good stability. In particular, the linear motor has good stability in linear motion. It is suitable for use as a push lock for new energy batteries in charging cabinets and is a structural improvement of similar products. Attached Figure Description

[0020] The structure and use of this utility model will now be further described with reference to the accompanying drawings. Figures 1-7 As shown, the housing of this new energy battery push lock is equipped with a locking hook 4 that can be unlocked by swinging or locked by collision. The housing includes a lock shell 1 and a shell cover 11. The two sides of the housing are symmetrically provided with sliding holes 101 to facilitate the linear movement of the top plate 10. The top plate is extended from both sides by a guide rod 9 that is integrated at one end of the top plate and inserted into the sliding holes on both sides of the housing. The pin hole 1002 at the other end of the top plate is connected to the pin 602 at the protruding end of the screw 601 of the linear motor 6 inside the housing, which serves as the moving shaft. The linear motor is fixedly installed inside the housing. One end of the guide post 5 inside the housing passes through the guide hole 1001 on one side of the top plate. The front end of the guide hole on the top plate, which is in a straight line, is provided with a bend hole 1003 to drive the locking hook inside the housing to rotate. The other end is connected to the guide post hole 401 on one side of the middle of the lock hook. The other side of the middle of the lock hook is connected to the screw 3 through the screw hole 402. The screw is fixedly set in the housing below the lock hook. A torsion spring 2 is provided at the screw for the lock hook to swing and reset. The hook part of one end of the lock hook under the top plate extends out of the housing and engages with the hook shaft 1201 on one side of the battery end shell 12. When unlocking, the linear motor pushes the top plate forward through the pin shaft. At the same time, the guide hole of the top plate pushes the guide post from the bend position of the guide hole into the straight position and changes direction, causing the lock hook to rotate. The hook part of the lock hook disengages from the hook shaft of the battery end shell. When the battery is placed in the cabinet, it collides with the lock hook through the hook shaft of the battery end shell, and the lock hook swings and resets to engage. The outer diameter of the top plate is aligned with the outer diameter of the battery end shell. The top plate continues to move forward to push out the battery in the cabinet.

[0021] The aforementioned housing contains a first micro switch 7 and a second micro switch 8. When the top plate inside the housing moves linearly to one end of the sliding hole, it triggers the corresponding first or second micro switch. The linear motor, the first micro switch, and the second micro switch are connected to the circuit board via wiring. Specifically, the first and second micro switches are respectively located on the inner wall of one side of the sliding hole inside the housing. When the top plate inside the housing moves linearly to one end of the sliding hole, the top plate triggers the corresponding first or second micro switch below it via a guide rod on that side.

[0022] The protruding part of the aforementioned lock hook housing is provided with a side lug 102 for limiting the swing of the lock hook. The side lug is a rolled edge formed by stamping and bending of the lock housing, or a rolled edge arranged symmetrically. The other end of the lock hook is raised outward and protrudes from the through hole 103 on one side of the housing, thereby facilitating the manual operation of the lock hook swing when the rear of the cabinet is opened, or facilitating the locking end of the lock hook to abut against the corresponding component inside the cabinet for limitation.

[0023] In the above structure, the top plate and the lock hook of the new energy battery push lock are arranged vertically inside the lock housing. The lock cover is fixed to the top of the lock housing with four symmetrically arranged mounting ears. The linear motor mounting area at the bottom of the lock housing has a stamped boss to facilitate the installation of the linear motor. The linear motor adopts a combination of a motor and a screw (T-type screw and sleeve), or other structures that ensure the linear movement of the screw. The two ends of the lock hook are symmetrically arranged at 90 degrees, but are not limited to the above angle, as long as the top plate is hinged to the guide post in the middle, one end has a hook, and the other end protrudes from the housing. The top plate is rectangular, one end of the top plate is bent by stamping, and the bottom of the stamped "Z"-shaped groove of the other end of the top plate is connected to the outer diameter key surface of the guide rod by screws.

[0024] When locking, the battery pushes the top plate to reset, or the top plate is already in the reset position via a linear motor, with the guide post located at the bend in the top plate. The battery moves into the casing and encounters the locking hook, causing the guide post of the locking hook to swing. After the battery is in place, the locking hook, under the force of the torsion spring, resets itself, and the hook part engages with the hook shaft of the battery end shell. When unlocking, the linear motor pushes the top plate forward, and simultaneously, the guide hole in the top plate pushes the guide post from the bend in the guide hole into the straight position and changes direction, causing the locking hook to rotate and unlock. After unlocking, the top plate continues to move forward, finally pushing out the battery.
