Description

Technical Field

[0001] This utility model relates to the field of charging device technology, and in particular to a fastener charging unit and management cabinet. Background Technology

[0002] Railway anti-slip devices generally need to be stored uniformly after use. For ease of management, a dedicated management cabinet for storing railway anti-slip devices can be used. As for the storage of fasteners, due to their special structure that facilitates hanging, multiple fasteners are usually neatly arranged and hung inside the cabinet cavity.

[0003] With the development of intelligent management, some railway anti-slip devices need to have built-in electronic equipment and power supplies. Therefore, the management cabinets used to store and manage railway anti-slip devices have also been equipped with circuit components. For example, the structure disclosed in patent CN 222247205 U has separate charging racks for iron shoes and fasteners. However, in the prior art, after placing fasteners and other devices, such management cabinets still need to be connected to charging equipment (or charging units) separately, which makes operation inconvenient and prone to errors due to too many manual operation steps. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a fastener charging unit and management cabinet. The fastener charging unit can meet the user's convenient charging needs and is not easy to make mistakes during operation.

[0007] The effect is as follows: users simply align the fastener's hook with the suspension unit and hang it up. Due to the guiding effect of the suspension unit, the fastener automatically adjusts its position, bringing the battery close to and making near-contact with the contact charging unit. Then, the contact charging unit transfers electrical energy after contact with the battery. Once charging begins, the external circuit regulates the voltage and current via the control module. This eliminates the need for users to plug and unplug the charging cable, reducing operation time and human error. Furthermore, the overall structure of the suspension beam is compact and can be integrated into various devices, such as tool cabinets or workstations, improving space utilization and equipment management efficiency.

[0008] Furthermore, the suspension part is a notch provided on the upper part of the suspension beam, and the width of the notch matches the width of the clamping claw of the fastener.

[0009] Furthermore, the notch includes a left notch and a right notch arranged sequentially along the length of the suspension beam.

[0010] Furthermore, the suspension beam includes a panel, a top plate that bends and extends above the panel, and a bottom plate that bends and extends below the panel. An opening is provided on the panel to expose the contact charging unit.

[0011] Furthermore, the suspension portion is provided at the junction of the top plate and the panel.

[0012] Furthermore, the suspension beam is also provided with a fixing plate and an insulating plate, and the contact charging part is constructed as a contact charging protrusion; the fixing plate is located on the side of the panel away from the fastener, the insulating plate is located on the side of the fixing plate facing the panel and exposed at the opening of the panel, and the contact charging protrusion is inserted through the insulating plate.

[0030] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0031] See Figures 1-3 This utility model provides a fastener charging unit 100 and a management cabinet 200.

[0032] A fastener charging unit 100 according to an embodiment of this application includes a suspension beam 110, which can be made of metal (such as aluminum alloy or stainless steel) or high-strength engineering plastic. A suspension part 11 is provided on the suspension beam 110. This embodiment utilizes the structural characteristics of the fastener itself, namely, hooks are provided at both ends of the fastener, so that the fastener is stably suspended by engaging with the hook on either side. Of course, the suspension part 11 can be a simple hook-shaped structure or a groove, and its shape and size are optimized according to common specifications of fastener hooks, such as using an arc or bevel design, to facilitate quick hooking and unhooking of the fastener by the user. Figure 1 As shown, the suspension part 11 is a slot.

[0033] Meanwhile, a contact charging section 12 is provided on the side of the suspension beam 110 facing the suspension fastener. This contact charging section 12 can be a wireless charging structure (or an inductive charging structure, i.e., charging via electromagnetic effect) or a contact charging structure. The contact charging section 12 is connected to an external circuit (not shown in the figure) via internal wiring. The external circuit may include a power adapter, a control module, and protection circuits, such as overcurrent protection or temperature monitoring, to provide a stable DC or AC power supply. When the fastener is suspended on the suspension part 11, the battery mounted on the fastener directly contacts the contact charging section 12, forming a closed circuit; specifically, the battery can be as follows: Figure 1 The device shown has a contact-type charging interface, and can also be equipped with a wireless charging structure that generates an electromagnetic induction effect to adapt to different contact charging structures and achieve battery charging.

[0034] In this way, the user only needs to align the fastener's hook with the suspension part 11 and hang it up. Due to the guiding effect of the suspension part 11, the fastener will automatically adjust its position so that the battery comes close to and makes contact or near contact with the contact charging part 12. Then, electrical energy is transferred through the contact charging part 12 after contact with the battery. After charging starts, the external circuit regulates the voltage and current through the control module. This avoids the user's need to plug and unplug the charging cable, reducing operation time and human error. Furthermore, the overall structure of the suspension beam 110 is compact and can be integrated into various devices, such as tool cabinets or workstations, improving space utilization and equipment management efficiency.

[0035] It should be noted that the "contact charging section 12" in this application embodiment refers to the battery of the fastener being brought close to it at a certain distance to form a charging connection, rather than narrowly referring to the requirement of direct physical contact for charging. That is, this application utilizes the fact that after the fastener itself is hung on the suspension beam 110, the area where the battery is located will naturally contact or substantially contact the suspension beam 110, thereby setting up the contact charging section 12 in the corresponding area to achieve fast and convenient charging, rather than being limited to close physical contact.

[0036] For example, in some embodiments, the contact charging unit 12 is configured as an inductive charging structure. The inductive charging structure, based on the principle of electromagnetic induction, enables energy transfer through basic contact, i.e., charging occurs when the battery is brought close enough to establish a charging connection. The inductive charging structure mainly includes a transmitting coil and a magnetic core. The transmitting coil is made of multi-strand enameled copper wire and is installed inside the suspension beam 110, typically on the side of the panel 13 facing the fastener, and protected by an insulating encapsulation (such as epoxy resin potting). The magnetic core is made of ferrite material to enhance magnetic field coupling and reduce energy loss. The transmitting coil is connected to an external circuit, including a high-frequency inverter (e.g., converting DC to AC) and a control unit, typically operating at a frequency between 100-400 kHz. When the fastener is suspended, its built-in receiving coil aligns with the transmitting coil, generating current through electromagnetic induction to charge the battery. The inductive charging structure may integrate position detection functionality (such as a Hall sensor) to ensure that charging is activated only when the fastener is in place, improving safety.

[0037] Correspondingly, the external circuit provides high-frequency alternating current to the transmitting coil, generating an alternating magnetic field. This magnetic field penetrates the surface of the suspension beam 110 and couples with the receiving coil in the fastener, inducing a current at the receiving end, which is then rectified to charge the battery. During charging, the control unit monitors the coupling efficiency via a communication protocol and dynamically adjusts the power output to avoid overheating or efficiency degradation. Understandably, in dusty or humid environments, inductive charging eliminates the need for physical contact, reducing wear and short-circuit risks. Therefore, users do not need to precisely align the contacts to achieve charging. Furthermore, the inductive charging structure has high environmental adaptability, can be used in waterproof applications, and eliminates the risk of sparks, enhancing safety.

[0038] In some embodiments, reference is made to Figure 1 As shown, the suspension part 11 is a notch located on the upper part of the suspension beam 110. The width of this notch precisely matches the width of the fastener's jaws to ensure accurate positioning of the fastener during suspension. The shape of the notch can be U-shaped, V-shaped, or rectangular, and its specific dimensions are designed according to the specifications of common fastener jaws to accommodate different models of fasteners. The notch can be directly formed on the suspension beam 110 through stamping, cutting, or injection molding processes, with its edges chamfered or polished to prevent scratching the fastener surface. In some examples, the notch is located at the top or side of the suspension beam 110 for easy user suspension of the fastener. Then, when the fastener's jaws are inserted into the notch, the jaws fit tightly against the inner wall of the notch due to the width match, forming a limiting position.

[0039] More specifically, the notches include a left notch 111 and a right notch 112 arranged sequentially along the length of the suspension beam 110. The left notch 111 and the right notch 112 are spaced a certain distance apart along the length of the suspension beam 110 to facilitate engagement with the hooks located on both sides of the fastener in the direction of the fastener's claws, achieving rapid positioning; for example, the fastener disclosed in the applicant's earlier application with patent number CN202510922455.7 has left and right claws that are respectively adapted to engage the left notch 111 and the right notch 112.

[0040] refer to Figures 1-2 As shown, the suspension beam 110 specifically includes a panel 13, a top plate 131 that bends and extends above the panel 13, and a bottom plate 132 that bends and extends below the panel 13.

[0041] Panel 13 is formed by bending to create a top plate 131 and a bottom plate 132, and has a certain thickness to balance strength and weight. An opening is provided on panel 13; this opening can be any shape, such as circular or square, and its size is designed according to the size of the contact charging part 12, exposing the contact charging part 12 so that it directly faces the suspension fastener. A sealing ring or insulating layer can be provided at the edge of the opening to prevent dust, moisture intrusion, or electrical short circuits. In this example, the bending angle of the top plate 131 and the bottom plate 132 is 90 degrees. Of course, the angle can be adjusted; for example, the top plate 131 can be bent at an angle to guide the suspension, and the bottom plate 132 can be bent horizontally for easy installation on other devices.

[0042] Understandably, panel 13 serves as the primary load-bearing surface to support the suspension unit 11 and the contact charging unit 12, while top plate 131 and bottom plate 132 enhance overall rigidity. When the fastener is suspended, the openings on panel 13 ensure unobstructed contact between the contact charging unit 12 and the battery.

[0043] The suspension unit 11 is located at the junction of the top plate 131 and the panel 13 to provide stable suspension support based on the turning point of the beam. For example... Figure 1 The notch can be directly cut at the junction to bear the weight and operating force of the fastener. Thus, when the user suspends the fastener, the hook slides into the notch along the slope for quick positioning. Therefore, the suspension part 11, located at the junction, utilizes the structural strength of the beam, reduces stress concentration, and extends service life. When the fastener is suspended, the suspension part 11 at the junction provides multi-directional support, preventing the fastener from swaying back and forth or moving laterally, thereby maintaining the stability of the charging contact.

[0044] Continue to refer to Figure 1 and Figure 2 As shown, a fixing plate 14 and an insulating plate 15 are also provided on the suspension beam 110. In this example, the specific structure of the contact charging part 12 is described as a contact charging protrusion.

[0045] The fixing plate 14, typically made of metal, is bolted or welded to the side of the panel 13 away from the fastener. Its main function is to provide structural support and a mounting base. The insulating plate 15, made of insulating material such as engineering plastics, ceramics, or composite insulating materials, is located on the side of the fixing plate 14 facing the panel 13 and is exposed through an opening in the panel 13. The dimensions of the insulating plate 15 match the opening, and its surface can be coated with an insulating coating to prevent electrical short circuits and environmental impacts. The charging contact protrusion is located inside the insulating plate 15 and is typically made of copper alloy or gold-plated metal. It is columnar, needle-shaped, or hemispherical. In this example, it is a columnar protrusion with a hemispherical end, slightly higher than the surface of the insulating plate 15, to ensure reliable contact with the fastener battery.

[0046] Therefore, when the fastener is suspended on the suspension part 11, the battery's charging contacts make physical contact with the exposed charging protrusions, forming a conductive circuit. The insulating plate 15 provides electrical isolation, preventing short circuits caused by metal components such as the fixing plate 14, while also providing mechanical protection and reducing wear on the contacts. The fixing plate 14 enhances the overall structural strength, withstanding mechanical stress during suspension and operation. During charging, the external circuit transmits electrical energy through the charging protrusions and can integrate sensors to monitor the contact status, ensuring charging stability.

[0047] In some embodiments, the suspension beam 110 also includes an RFID antenna cover 16 and an RFID antenna 17 integrated therein. It can be mounted on the panel 13 by adhesive or snap-fit, and its dimensions are designed according to antenna requirements for wireless communication with RFID tags on the fastener. The RFID antenna 17 is connected via cable to an external reader / writer, which may integrate a processor and database for identifying and managing the fastener. In this example, the RFID antenna cover 16 is located on the side of the panel 13 away from the fastener, and the panel 13 has a second through-hole at its center to expose the RFID antenna 17 and improve detection efficiency.

[0048] In this way, when the fastener is suspended on the suspension part 11, the RFID antenna 17 reads the information (such as device ID, battery status, or usage record) of the RFID tag on the fastener through electromagnetic induction and sends the data to an external system. During charging, the RFID system works in conjunction with the charging control module. For example, charging is only initiated when an authorized RFID tag is detected; if no tag is detected, power is not supplied to ensure the electrical safety of the device. This allows users to monitor the device status in real time via RFID data, and to charge only when a fastener is detected. It also allows recording the time the fastener is used and returned, reducing human error.

[0049] Furthermore, in Figures 1-2In the corresponding example, each suspension beam 110 is provided with multiple suspension parts 11 and contact charging parts 12, and a partition 18 is provided between each pair of suspension parts 11 and contact charging parts 12; thus, several charging spaces are separated by the partition 18, and each charging space is provided with a pair of suspension parts 11 and contact charging parts 12, suitable for charging one fastener. This avoids the user from accidentally connecting the fastener to two different charging areas, which could lead to a short circuit.

[0050] According to the management cabinet 200 of the embodiments of this application, refer to Figure 3 As shown, it is equipped with the fastener charging unit 100 described in any of the aforementioned embodiments. Below the fastener charging unit 100, a support plate 210 is also provided, which supports the fastener to prevent excessive stress concentration at the hook of the fastener.

It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge.
