Description

Technical Field

[0001] This utility model relates to the field of microcomputer anti-misoperation equipment technology, and in particular to a computer key. Background Technology

[0002] In the power industry, computer-controlled interlocking keys with anti-misoperation features are core equipment for ensuring on-site operational safety. To improve ease of use and environmental adaptability, existing computer keys generally integrate wireless charging functionality. The internal wireless charging coil and induction structure are typically built into the back of the casing, enabling charging without physical contacts. However, current technology for computer keys supporting wireless charging has significant technical drawbacks. First, the battery is often internally fixed, requiring force to be applied to the wireless charging module area on the back of the casing during replacement. This can easily lead to coil displacement, deformation, or loosening of the wiring, affecting charging performance and even causing functional failure. Furthermore, the battery's lifespan is tied to the device's. When the battery is damaged due to aging, bulging, or harsh environments, the device is difficult to repair quickly, often requiring complete scrapping, resulting in high operating costs and complex disassembly and assembly operations, hindering rapid on-site maintenance.

The battery 220 is detachably installed within the bracket 210 along the second direction S2 through the first opening 130 and the second opening 211. It should be noted that the first direction S1 is the length direction of the housing 100, and the second direction S2 is the width direction of the housing 100, which is the direction in which the battery 220 is pushed in laterally. The first direction S1 and the second direction S2 are perpendicular.

[0026] This invention provides a first opening 130 on the side of the housing 100, connecting the receiving cavity 110 to the external environment, and a second opening 211 on the bracket 210 facing the first opening 130. This allows for the horizontal installation and removal of the battery 220. When replacing the battery 220, it is not necessary to touch the wireless charging module area on the back of the housing 100. This helps avoid problems such as coil displacement, deformation, or loosening of the wiring during battery 220 replacement, ensuring long-term stable wireless charging function, reducing maintenance costs, and extending the lifespan of the computer key. Furthermore, by providing a removable battery 220 within the bracket 210, when the battery 220 ages, bulges, or is damaged, only the battery 220 needs to be replaced, eliminating the need to discard the entire computer key and preventing the lifespan of the battery 220 from being tied to that of the computer key.

[0027] It is understood that the bracket 210 can be fixedly installed in the receiving cavity 110 or detachably installed in the receiving cavity 110.

[0028] like Figure 2 As shown, the battery 220 includes an electrical interface 221, such as a blade-type interface. The bracket 210 also has a third opening 212 for avoiding the electrical interface 221. The third opening 212 is oriented away from the side where the first opening 130 is located. The shape of the third opening 212 is adapted to the shape of the electrical interface 221, through which the electrical interface 221 is electrically connected to the electrical components of the computer key.

Preferably, the inner wall of the guide portion 213 is provided with a wear-resistant coating to reduce frictional wear between the guide portion 213 and the battery 220 ribs during battery insertion or removal, thereby extending the service life of the guide portion 213.

[0030] like Figure 2As shown, a flexible traction member 222 is also provided on either side of the battery 220 away from the electrical interface 221. At least a portion of the structure of the flexible traction member 222 is exposed outside the second opening 211. Pulling the flexible traction member 222 can pull the battery 220 out of the bracket 210. This utility model's technical solution, by providing a flexible traction member 222 on either side of the battery 220 away from the electrical interface 221, with at least a portion of the structure of the flexible traction member 222 exposed outside the second opening 211, allows for manual and quick removal of the battery 220 when it needs to be replaced, without the need for specialized tools. This is particularly suitable for emergency power maintenance scenarios. Preferably, the flexible traction member 222 is a thin rope adhered to the bottom of the battery 220. The rope is flexible and tough, occupying less space when contracted within the receiving cavity 110, improving the compactness of the internal structure of the receiving cavity 110, while also possessing the toughness to pull the battery 220 out of the bracket 210.

[0031] Preferably, the opening dimensions of the first opening 130 and the second opening 211 in the third direction S3 are matched with the thickness clearance of the battery 220. The dimensions of the bracket 210 are adapted to the dimensions of the battery 220.

[0032] like Figure 2 As shown, the cover plate 120 is provided with at least two first connecting portions 121 on the side facing the receiving cavity 110, and the housing 100 is provided with a second connecting portion corresponding to the first connecting portions 121 on the side near the cover plate 120. The first connecting portions 121 and the second connecting portions are detachably connected to detachably connect the cover plate 120 and the housing 100.

[0033] Preferably, either the first connecting part 121 or the second connecting part is a snap fastener, and the other is a slot that matches and connects with the snap fastener. The end of the snap fastener is provided with a barb structure, which engages and limits the corresponding slot.

[0034] like Figure 2 As shown, the cover plate 120 is also provided with a connector 122, and the housing 100 is provided with a connection hole that corresponds to and matches the connector 122. The connector 122 is detachably connected to the connection hole to detachably connect the cover plate 120 and the housing 100. Preferably, the connector 122 is a screw, and the connection hole has a thread that matches the screw.

[0035] like Figure 2As shown, an adhesive member 123 is also provided on the side of the cover plate 120 facing the housing 100, and at least a portion of the structure of the adhesive member 123 is continuously arranged along the inner contour of the cover plate 120. This utility model's technical solution, by providing an adhesive member 123 on the side of the cover plate 120 facing the housing 100, with at least a portion of the structure of the adhesive member 123 continuously arranged along the inner contour of the cover plate 120, facilitates further achieving a tight seal and improves waterproof and dustproof performance. Preferably, the adhesive member 123 is a double-sided adhesive with a ring-shaped structure, surrounding the area between the inner edge of the cover plate 120 and the first connecting portion 121. The adhesive member 123 can also be segmented on the side of the cover plate 120 facing the housing 100.

[0036] like Figure 2 As shown, the battery assembly 200 also includes an electromagnetic shielding component 230, which is disposed between the battery 220 and the cover plate 120. This invention, by placing the electromagnetic shielding component 230 between the battery 220 and the cover plate 120, can both buffer vibration and prevent the battery 220 from loosening, and shield electromagnetic interference, ensuring the stability of the computer key in complex electrical environments. Preferably, the electromagnetic shielding component 230 is conductive foam, which has a rectangular block structure. The area of ​​the conductive foam is not less than the surface area of ​​the battery 220 facing the cover plate 120, and the thickness of the conductive foam is 1-3 mm.

[0037] Preferably, the computer key also includes a battery status detection module, housed within the housing 100 and electrically connected to the battery 220, to detect the performance of the battery 220. For example, the battery status detection module can be integrated onto the main control circuit board. This module includes a voltage sensor, a current sensor, and a data processing unit. The voltage sensor detects the battery 220 voltage in real time, the current sensor monitors the charging and discharging current, and the data processing unit analyzes the detection data, quantifies the remaining capacity of the battery 220, assesses the degree of aging of the battery 220 according to predetermined logic, and displays relevant information on the computer key's display screen. When the performance of the battery 220 approaches the failure threshold, an indicator light alarm is triggered, allowing the user to replace the battery 220 in advance and avoid sudden on-site failures. This utility model's technical solution, by setting a battery status detection module to monitor the performance of the battery 220 in real time, can quantify the degree of aging of the battery 220 and predict failure points, avoiding on-site operation interruptions caused by sudden battery failure, solving the problem of blind maintenance, and improving operational safety.

[0038] The following describes the process of removing and installing the battery 220 in the computer key in this embodiment.

[0039] When removing the battery 220, first loosen the connector 122 (screw) on the cover plate 120, press the buckle to release the engagement with the slot, remove the cover plate 120, and pull the exposed flexible traction member 222 to pull the battery 220 out from the second opening 211 of the bracket 210 and the first opening 130 of the housing 100.

[0040] When installing the battery 220, push the battery 220 laterally into the bracket 210 along the guide part 213 in the second direction S2. The electrical interface 221 passes through the third opening 212 and connects with the main control circuit board. Cover the cover plate 120, first use the buckle to snap into the slot for positioning, and then tighten the connector 122 (screw) to fix it. The adhesive part 123 on the inner ring of the cover plate 120 achieves a sealed fit.

[0041] This utility model's technical solution involves the horizontal disassembly and reassembly of the battery 220. When replacing the battery 220, there is no need to touch the wireless charging module area on the back of the housing 100. This helps avoid problems such as coil displacement, deformation, or loosening of the wiring during battery 220 replacement, ensuring long-term stable wireless charging functionality, reducing maintenance costs, and extending the lifespan of the computer key. By incorporating a removable battery 220 within the bracket 210, when the battery 220 ages, bulges, or is damaged, only the battery 220 needs to be replaced, eliminating the need to scrap the entire computer key and preventing the lifespan of the battery 220 from being tied to that of the computer key.
