[0002] With the popularity of electric vehicles, the safety and reliability of charging guns, as the core components of electric vehicle charging equipment, have received increasing attention. Existing charging guns generally rely on a mechanical locking structure to lock and unlock the gun body and the charging device. However, there are many problems with the traditional mechanical locking structure. For example, it is prone to mechanical wear after long-term use, which causes the locking mechanism to fail, thus affecting the normal use of the charging device. In addition, the waterproof and dustproof capabilities of the traditional mechanical locking structure are limited. When used outdoors, it is easily affected by the external environment (such as rain, dust, etc.), which in turn affects the reliability of the lock body and even causes safety hazards during the charging process.

[0003] The existing unlocking mechanism of charging guns usually relies on manual operation. In emergency situations, such as power outages or lock failures, this method may not be able to unlock in time, causing inconvenience or even safety risks to users. Therefore, the market urgently needs a charging gun electronic lock with high protection performance and the ability to unlock in emergency situations, so as to improve the safety, durability and ease of use of the charging gun.

[0007] The electronic lock face cover and the electronic lock bottom cover match each other and are fixed by fasteners to form an electronic lock housing;

[0008] A motor, a switch assembly and a rotating block are installed inside the electronic lock housing. The switch assembly is installed above the motor. The motor drives the rotating block to rotate. The rotating block is used to press or release the switch assembly by rotating. The lower end of the unlock button abuts against the rotating block. The emergency unlock button is used to push the rotating block to rotate by lateral movement.

[0009] The protective silicone sheet includes a silicone substrate, a silicone convex block and a silicone mounting seat. The protective silicone sheet is an integrated molding design. The silicone convex block is fixed to the upper surface of the silicone substrate. The silicone mounting seat is fixed to one side of the silicone substrate. A mounting cavity is formed in the silicone mounting seat. A mounting position matching the shape of the lower end of the protective silicone sheet is formed on the electronic lock surface cover.

[0010] The silicone mounting seat is formed with a silicone ring for the emergency unlocking button to pass through; the unlocking button is installed on the upper side of the protective silicone sheet and passes through the electronic lock surface cover, and the silicone protrusion is provided with a through hole for the unlocking button to pass through;

[0011] The protective silicone sheet is covered with a silicone pressing sheet, the silicone pressing sheet is provided with a through groove corresponding to the silicone protrusion, and a mounting block installed in the mounting cavity of the silicone mounting seat, and the mounting block is provided with a mounting groove for mounting the silicone ring.

The unlock button is combined with the electronic lock cover through the silicone protective sheet. The user can feel clear pressing feedback when using it, and the operation is easier and more intuitive. The limiting effect of the second push block avoids accidental unlocking and ensures the safety of operation. The design of the emergency unlock button provides users with additional safety protection in emergency situations and enhances the reliability of the charging gun in complex environments.

Even when the electronic system fails, the user can still unlock the device through the emergency unlock button, increasing the emergency reliability of the device.

[0034] The protective silicone sheet covers the electronic lock cover, and the silicone bumps can effectively prevent water, dust and other external impurities from entering the interior of the electronic lock, improving the protection performance of the lock body. The silicone substrate, silicone bumps and silicone mounting seat are integrally formed, which not only improves the sealing and protects the internal electronic components from the external environment, but also improves the durability of the electronic lock and adapts to various usage environments. The unlock button is combined with the electronic lock cover through the silicone protective sheet. The user can feel clear pressing feedback when using it, and the operation is easier and more intuitive.

[0037] High reliability and strong safety: The limiting effect of the second push block 42 can effectively prevent the misoperation of the unlocking button 7 in the locked state, ensuring that the charging gun is stably locked on the charging pile during the charging process. In addition, the coordinated use of the spring 62 and the first push block 41 further enhances the stability and smoothness of the locking and unlocking process.

[0038] The protective silicone sheet covers the electronic lock cover, and the silicone protrusion can effectively prevent water, dust and other external impurities from entering the electronic lock, thereby improving the protection performance of the lock body. The motor drives the rotating block to achieve locking and unlocking, and the unlocking button cooperates with the charging gun lock hook to ensure that the charging gun is locked stably, unlocked smoothly, and easy for users to operate. Emergency unlocking function: The setting of the emergency unlocking button can be manually unlocked in the event of power failure or system failure, ensuring that the lock can still be released smoothly in an emergency, thereby improving the safety and reliability of the system. Simplified operation and maintenance: The protective silicone sheet design is combined with the silicone protrusion, and the unlocking button is easy to operate through the through hole of the silicone sheet, and the protective silicone sheet can be easily disassembled and replaced, which is convenient and quick to maintain. The present invention ensures that the charging gun will not be misoperated or unauthorizedly unlocked during use through the automatic locking and unlocking mechanism of the electronic lock, thereby ensuring the safety of the charging process, and is particularly suitable for high-power charging scenarios. The dual feedback design of the mechanical switch and the signal switch ensures that the locking and unlocking status of the electronic lock is monitored and fed back in real time, thereby increasing the reliability of the device. The motor drives the automatic locking and unlocking operation. Users only need to insert or remove the charging gun to complete the operation without manual locking or unlocking, which improves the user's convenience. Even when the electronic system fails, users can still unlock the device through the emergency unlock button, which increases the emergency reliability of the device.

[0039] In order to ensure that the deformation of the silicone substrate 31 under the maximum load does not exceed the allowable value, while meeting the requirements of lightweight and structural strength, the stability and reliability of the electronic lock in various usage environments are ensured.

[0040] The thickness of the silicone substrate 31 is configured. The mathematical model for configuring the thickness of the silicone substrate 31 is:

[0041]

[0042] Wherein, t: thickness of silicone substrate; F: maximum load; L: length of silicone substrate; W: width of silicone substrate; E: elastic modulus of silicone material; ν: Poisson's ratio of silicone material; δmax: maximum allowable deformation;

[0043] The configuration steps include:

[0044] The optimal thickness is determined by finite element analysis, with the goal of minimizing the thickness t of the silicone substrate while ensuring that the deformation δ under the maximum load F is less than the threshold δmax;

[0045] Stress and strain relationship of silicone substrate:

[0046] According to Hooke's law, the relationship between stress σ and strain ε is:

[0047] σE·ε

[0048] Calculation of deformation of silicone substrate 31:

[0049] The center point deformation δ of the rectangular plate of the silicone substrate 31 under the four-side fixed constraint is expressed as:

[0050]

[0051] Where I is the moment of inertia of the section, for a silicone substrate 31 rectangular cross section:

[0052]

[0053] Silicone substrate 31 optimization goals:

[0054] Minimize the thickness t while satisfying:

[0055] δ≤δmax

[0056] Substitute the deformation formula into the optimization objective:

[0057]

[0058] After simplification, we get:

[0059]

[0060] The final optimization formula is:

[0061]

[0062] Take an example to illustrate the specific parameters and calculations:

[0063] Assumptions:

[0064] Maximum load: F = 100N;

[0065] Silicone substrate size: L = 50mm, W = 30mm;

[0066] Maximum allowable deformation: δmax = 0.5mm;

[0067] Substituting into the formula:

[0068]

[0069] Calculation results:

[0070]

[0071]

[0072]

[0073] t10.99mm

[0074] The optimal thickness of the silicone substrate 31 is determined by finite element analysis (FEA) and the above mathematical model. This thickness can provide sufficient support to ensure that the deformation under the maximum load does not exceed the allowable value, and will not increase excessive weight, thus meeting the overall technical solution requirements of this application. This optimized design ensures the stability and reliability of the electronic lock in various usage environments.

[0075] Also included is an embodiment of a charging gun, based on the previous embodiment, such as Figure 2 As shown, the charging gun body 10 and the charging gun lock hook 101 are formed in the charging gun body 10 to accommodate the electronic lock for the charging gun. The middle part of the charging gun lock hook 101 is connected to the charging gun body 10 for limited rotation. The unlocking button 7 is against the lower end of the rear side of the charging gun lock hook 101. The charging gun lock hook 101 is also used to close the cavity of the charging gun body 10. The charging gun lock hook 101 is formed with an unlocking rod that can replace the unlocking button 7. There are two options. One is to unlock by a separate unlocking button. Since the unlocking button is an independent component, if it is damaged or worn, only the unlocking button needs to be replaced without replacing the entire lock hook assembly. The maintenance cost is low and the operation is simple. The second is to directly fix the unlocking button on the charging gun lock hook 101 (i.e., the unlocking rod), and the unlocking rod is integrated with the charging gun lock hook, which simplifies the overall design, reduces the need for independent buttons, and improves the compactness and integration of the charging gun.

[0076] The limited rotation connection between the charging gun lock hook 101 and the charging gun body 10 can ensure that the charging gun remains stable during the insertion and removal process to avoid looseness or wrong connection. The charging gun is effectively prevented from falling off, and the safety of the charging gun during the charging process is improved. The unlocking button 7 is against the lower end of the rear side of the charging gun lock hook. The charging gun can be automatically unlocked by pressing the unlocking button, which reduces the complexity of manual operation and improves the efficiency of unlocking. The charging gun lock hook can not only lock the charging gun, but also ensure that the user can smoothly pull out the charging gun through the cooperation of the unlocking button, which is convenient to operate. The charging gun lock hook is used to close the cavity of the charging gun body to ensure that the electronic lock and other internal components in the cavity will not be affected by the external environment, such as dust, rain, etc. during the charging process, thereby improving the overall protection performance of the charging gun. By combining the unlocking button (7) with the charging gun lock hook (101), the structure is compact and the operation is simple. The user only needs to press the button to complete the unlocking action, which reduces the complicated operation steps of the traditional mechanical lock and makes the user experience more convenient. The unlock button 80 abuts against the lower rear end of the charging gun lock hook 1012. When the unlock button 80 is locked, the charging gun lock hook 1012 is also restricted and cannot rotate.

[0077] In summary, the present invention provides an electronic lock system suitable for a charging gun, which realizes the electric operation of locking and unlocking the charging gun through the close cooperation between the electronic lock face cover and the electronic lock bottom cover, and through the reasonable layout of the rotating block, the motor, and the switch assembly. The design of the protective silicone sheet not only provides effective sealing protection, but also ensures the flexible operation of the unlocking button. The whole structure is compact and easy to install, which is suitable for charging gun usage scenarios in different environments. A protective silicone sheet is installed on the upper surface of the electronic lock face cover. The silicone sheet has a silicone bump and a through-hole design to ensure that the unlocking button passes smoothly when pressed, and can effectively resist the intrusion of dust, water and other substances in the external environment. Further design also allows additional silicone sheets to be covered on the protective silicone sheet to enhance the protection effect, which is particularly suitable for charging gun systems in outdoor or complex environments. The rotating block is driven by a motor to realize the automatic locking and unlocking process, and the operation can be quickly completed using the unlocking button, which is convenient for user operation. At the same time, the system also provides an emergency unlocking button, which can be manually unlocked in an emergency in the event of power or electrical failure to ensure safety and convenience. The electronic lock system is tightly integrated with the gun body and lock hook of the charging gun. The charging gun lock hook is connected to the charging gun body through limited rotation to ensure the stability of the locked state. At the same time, the lock hook is also used to close the cavity of the charging gun body to ensure that the internal electronic lock and related components are not affected by external factors, thereby improving the overall safety and durability of the charging gun. Through unified design and components, the electronic lock system facilitates the assembly and maintenance of the charging gun. The design of the protective silicone sheet and silicone bumps not only enhances the protection capability of the system, but also simplifies daily maintenance and replacement operations. Whether it is the initial installation or subsequent maintenance, the system can be easily disassembled and assembled, reducing labor costs.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate but not limit the technical solutions of the present invention, and any equivalent substitutions of the present invention and any modifications or partial substitutions that do not depart from the spirit and scope of the present invention should be included in the scope of protection of the claims of the present invention.
