Description

Technical Field

[0001] This invention belongs to the field of battery swapping equipment, and particularly relates to a battery swapping cabinet door structure with a battery anti-theft system. Background Technology

[0002] With the rapid development of the shared battery swapping industry, battery swapping cabinets, as core equipment for battery storage, charging, and exchange, have their anti-theft performance directly related to operational safety and property loss. Existing battery swapping cabinet door anti-theft designs have significant flaws: relying solely on electromagnetic locks and internal spring rods to achieve door closing and position detection results in an overly simplistic structure.

[0003] This single detection mechanism is easily cracked. Criminals can use simple tools such as screwdrivers to press the spring-loaded lever, creating the illusion that the compartment door is closed, thereby bypassing the anti-theft mechanism and stealing the batteries inside. Furthermore, the existing structure cannot effectively detect whether the compartment door has been damaged by external force or deformed, further reducing the reliability of the anti-theft measures. This not only causes direct property loss but also affects the market acceptance and operational efficiency of the battery swapping cabinet.

[0004] Therefore, designing a reliable anti-theft door structure with multiple detection mechanisms to address the shortcomings of existing battery swapping cabinets, such as false closure for theft and insufficient identification of tampering, is key to improving the security performance of battery swapping cabinets. Summary of the Invention

[0005] To address the problems of existing battery swapping cabinet doors having simple anti-theft structures, unreliable detection, and susceptibility to hacking and theft, this invention provides a battery swapping cabinet door structure with an integrated battery anti-theft system. Through a multi-protection design that combines magnetic detection with an electromagnetic lock, it achieves accurate detection of the door's closed state, thereby improving anti-theft reliability.

[0006] Core technology solutions

[0007] A battery swapping cabinet door structure with a battery anti-theft system includes a cabinet body, a battery charging compartment assembly, a magnetic anti-theft door assembly, and a control assembly. These components work together to achieve both charging and anti-theft functions.

[0008] The cabinet serves as the overall installation carrier, with control components mounted at the top and multiple battery charging compartment components arranged side by side at the bottom. Each battery charging compartment component is magnetically connected to a magnetic security door component.

[0009] The control component coordinates the charging start and stop of the battery swapping cabinet and the opening and closing status of the magnetic anti-theft door component. The magnetic anti-theft door component uses a magnetic detection mechanism to provide feedback on the actual closed status of the door.

[0010] When the magnetic security door assembly is closed, the magnetic structure and the detection probe form a conductive circuit, and the control component receives an electrical signal to confirm that the door is closed; if it is not closed or is falsely closed, there is no conductive signal, so it is determined that the door is not closed properly, triggering the anti-theft alarm.

[0011] Furthermore, the magnetic security door component has been optimized: it consists of a sheet metal fixing bracket, a magnetic switch magnetic component, a fixing nut, a door panel, a magnetic switch detection probe, and a probe fixing bracket. The sheet metal fixing bracket and the probe cabinet fixing bracket are set opposite to each other to ensure the accuracy of magnetic detection.

[0012] Furthermore, the battery charging compartment assembly includes a charging compartment cabinet support, a buffer strip, a compartment door panel connector, a charging compartment cabinet rear support, a charging valve support, and a charging valve. The buffer strip reduces collision damage when the battery is stored, and the charging valve is fixed to the back of the rear support by the support to ensure charging safety.

[0013] Furthermore, the heat dissipation of the control components has been upgraded by adding a heat dissipation component behind the second mounting panel, consisting of a fan bracket and multiple fans, which can quickly dissipate the working heat of the electronic control components and extend their service life.

[0014] Furthermore, auxiliary functions are provided, with a lighting and speaker assembly installed on the top of the cabinet, including LED light strips, speaker components, sound amplification holes and transparent light strips, to realize lighting and anti-theft alarm functions; support components are provided on the left and right sides of the bottom of the cabinet, along with caster assembly (including caster mounting plate, caster joint, axle and caster), to ensure both placement stability and ease of movement.

[0015] The beneficial effects of this invention are:

[0016] Enhanced anti-theft reliability: The dual mechanism of magnetic detection and electromagnetic lock completely eliminates theft by falsely closing the door and accurately identifies the true closed state of the door;

[0017] High structural stability: Each component is fixed with nuts, making the connection firm and effectively identifying deformation of the door caused by external force, further reducing the risk of theft;

[0018] Easy to install and use: The magnetic connection makes it easy for users to open and close the compartment door. The structure is simple to install, the detection signal is stable, and no complicated operation is required.

[0019] Functional integration: Integrates functions such as charging control, anti-theft detection, heat dissipation, and lighting alarm to improve the overall performance and market competitiveness of the battery swapping cabinet. Attached Figure Description

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0043] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0044] Example 1 (Basic Anti-theft Structure Example)

[0045] like Figure 1-11 As shown, this embodiment is the core basic form, which focuses on realizing magnetic anti-theft and closing detection functions, and is suitable for basic anti-theft scenarios.

[0046] The magnetic security door component 3 is the core security component, and its assembly process is as follows:

[0047] The sheet metal fixing bracket 31 is installed on the inside of the door panel 35 by the sheet metal fixing bracket fixing nut 34. The fixing nut is made of stainless steel to ensure the connection strength and prevent loosening after long-term use.

[0048] The magnetic switch magnetic component 32 is mounted on the sheet metal fixing bracket 31 by the magnetic switch magnetic component fixing nut 33. The magnetic component is made of neodymium iron boron strong magnetic material to ensure effective adsorption distance and detection stability.

[0049] The probe cabinet fixing bracket 38 is welded to the edge of the battery charging compartment assembly 2. The magnetic switch detection probe 36 is fixed inside the probe cabinet fixing bracket 38 by the probe fixing nut 37. The relative distance between the detection probe and the magnetic component is controlled within 5mm to ensure detection sensitivity.

[0050] Assembly of battery charging compartment assembly 2: The charging compartment cabinet bracket 21 is installed inside the cabinet 1, and 3-4 buffer strips 22 (made of EVA foam, 5mm thick) are pasted on the inner wall to reduce collision when the battery is placed in; the compartment door panel connector 23 is installed on the inner side of the charging compartment cabinet bracket 21 to connect the compartment door panel 35; the charging compartment cabinet rear bracket is bolted to the rear side of the charging compartment cabinet bracket, and the charging valve 26 is fixed to its back through the charging valve bracket 25. The charging valve 26 is an overload-proof model to ensure charging safety.

[0051] The core control logic of control component 4: The first mounting panel 45 is fixed to the head of the cabinet 1. The first circuit board 43, solenoid valve 42 and power switch 44 are installed on the front side from left to right. The air duct 46 is installed in front of the solenoid valve 42 for heat dissipation. The second mounting panel 412 is installed on the rear side of the first mounting panel 45. The wiring terminal 47, rechargeable battery bracket 48 and second circuit board 411 are arranged from right to left. The rechargeable battery 49 is placed on the bracket to provide backup power for the control component. The control compartment door panel 410 is installed at the head of the cabinet 1. The control panel 41 is embedded in it for user operation and status display.

[0052] Working principle: When the user closes the door panel 35, the magnetic switch magnetic element 32 of the magnetic anti-theft door assembly 3 moves close to the magnetic switch detection probe 36 along with the door panel 35. When the distance reaches the detection threshold (≤5mm), the detection probe forms a circuit, and the electrical signal is transmitted to the first circuit board 43 through the terminal 47. The control component 4 confirms that the door is actually closed and starts the charging program or maintains the anti-theft state. If the door is not closed or the electromagnetic lock is falsely pressed with a tool, the magnetic element and the detection probe do not form an effective proximity and there is no conduction signal. The control component 4 determines that the door is not closed properly, refuses to start charging, and prompts an abnormality through the control panel 41. If the door remains open, the subsequent alarm mechanism is triggered.

[0053] Example 2 (Example with heat dissipation and mobility functions)

[0054] like Figure 1-11As shown, based on Embodiment 1, a heat dissipation component 5 and a universal wheel component 8 are added, which is suitable for high-power charging and frequent movement usage scenarios, such as outdoor battery swapping stations and temporary charging sites.

[0055] Assembly and function of heat dissipation component 5: The fan mounting bracket 51 is installed behind the second mounting panel 412 inside the cabinet 1 by bolts. Two to three fans 52 (12V DC fans with an air volume ≥30CFM) are evenly distributed on the fan mounting bracket 51. The fans are electrically connected to the second circuit board 411. When the control component 4 detects that the internal temperature exceeds 45℃, the fan will be automatically started to dissipate heat and control the operating temperature of the electronic control components below 40℃ to avoid high temperature affecting performance or causing safety hazards.

[0056] Configuration of caster wheel assembly 8 and support component 7: Four support components 7 (made of carbon steel, 100mm high) are welded to the left and right sides of the bottom of the cabinet 1 for stable support when fixed; Four caster wheel assemblies 8 are installed in the middle of the bottom. The caster wheel mounting plate 81 of each caster wheel assembly 8 is fixed to the bottom of the cabinet with bolts. The universal joint 82 connects the caster wheel mounting plate 81 and the wheel axle 83. The caster wheel 84 is made of polyurethane, with a load-bearing capacity of ≥50kg and a braking function, which facilitates the overall movement of the power exchange cabinet and can lock the position when fixed to prevent slippage.

[0057] Example 3 (Full-Functional Integration Example)

[0058] Based on Example 2, a lighting and horn assembly 6 is added to achieve integrated lighting and alarm functions, which is suitable for nighttime use and unattended battery swapping stations.

[0059] Assembly of the lighting and horn assembly 6: LED light strip 61 is installed on the inner top of the cabinet 1 by a buckle, and a transparent light strip 64 is set directly below it for lighting during battery swapping. The LED light strip has a power of 5W and a color temperature of 4000K, and the lighting range covers all the openings of the battery charging compartment assembly 2. The horn 62 is installed on the side of the LED light strip 61, and multiple sound amplification holes 63 (3mm in diameter, evenly distributed) are opened at the corresponding positions on the cabinet 1 to ensure that the alarm sound is clearly transmitted.

[0060] Alarm triggering mechanism: The alarm function will be activated when control component 4 detects the following abnormal conditions:

[0061] The cargo door remained open for more than 30 seconds.

[0062] Abnormal magnetic detection signal (e.g., external force causing displacement of magnetic components);

[0063] The electromagnetic lock was forcibly pried open.

[0064] When the alarm is triggered, the speaker 62 emits a warning sound of over 80dB, and the LED strip 61 flashes red light, continuing the alarm until the anomaly is resolved or the staff handles the situation, further enhancing the deterrent effect of theft prevention and the efficiency of emergency response.

[0065] The above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also fall within the scope of the present invention, and the patent protection scope of the present invention should be defined by the claims.
