[0034] 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.

[0035] See Figures 1-7 This utility model provides a charging unit 100 and a management cabinet 200 for charging devices with mobile power supplies via contact points.

[0036] The charging unit 100 for contact charging of a device with a mobile power supply according to an embodiment of this application includes a frame 110 and a rocker 130 rotatably connected to the frame 110. The rotatable connection can be a hinge or other conventional connection method; of course, the two can be directly connected or indirectly connected, such as through a fixing plate 120.

[0037] The rocker arm 130 is a bent plate, with the acute angle of the bend facing the insertion direction of the device with the power bank. The middle portion of the rocker arm 130 is rotatably connected to the frame 110 along its length. One end of the rocker arm 130 has a charging contact protrusion 131, and the other end faces the insertion direction of the device with the power bank. That is, when the device with the power bank is inserted, it contacts one end portion and pushes the rocker arm 130 to rotate, causing the end portion with the charging contact protrusion 131 to rotate to the charging position and contact the device for charging. A reset member 140 is provided between the rocker arm 130 and the frame 110. The reset member 140 resets the rocker arm after the device is removed. Thus, when the user inserts the device (for simplicity, the device with the power bank will be referred to as the device), the end without the charging structure contacts the device and bears the force of insertion, while the end with the charging structure is moved towards the device.

[0038] Therefore, the charging unit of this embodiment, due to the setting of the contact charging structure, allows users to start charging simply by placing the device in, making the operation convenient; and, by utilizing the rotation of the rocker 130, the side of the rocker 130 with the contact charging protrusion 131 will rotate to contact the device after the device with the power bank is placed in the charging area. Therefore, the contact will not be impacted or rubbed during the device placement process, which can avoid wear and tear on the charging structure or a reduction in its service life due to long-term impact.

[0039] like Figures 1-4The rocker arm 130 is connected to the frame 110 via a fixing plate 120. In these embodiments, the charging unit 100 includes the frame 110 and a fixing plate 120 fixedly disposed inside the frame 110. It is worth noting that this application uses the fixing plate 120 connection as an example. Those skilled in the art, after reading this example, can easily conceive of using two or more plates to indirectly connect the rocker arm 130 to the frame 110, or alternatively, using a frame structure, limiting blocks, etc., instead of plates.

[0040] A rocker plate 130 is installed on the rear side of the fixing plate 120 by a rotatable connection. The front side of the fixing plate 120 is used to directly abut against a device with a power bank that needs to be charged. That is, after the device with a power bank is placed in the charging area, its end face abuts against the front side of the fixing plate 120 to achieve a limit.

[0041] The seesaw 130 is a bent board, and its middle part along its length is rotatably connected to the fixed plate 120 via a pivot 150.

[0042] In this embodiment, the middle portion refers to any position near the bending region within the bent plate, such as... Figure 5 In the example shown, the bend is closer to the end that is used to contact and push against the device, which can amplify the rotation range of the charging structure. Of course, other similar connection positions are also possible, such as direct connection to the bend.

[0043] The two ends of the rocker 130 have different functions: one end is connected to a charging circuit (not shown in the figure) and has a charging contact protrusion 131 on the side near the fixing plate 120 for contacting the charging interface of a power bank, such as the charging interface of a safety shoe; the other end faces the direction in which the device is inserted. When the device is inserted, it pushes this end, causing the rocker 130 to rotate, so that the end with the charging contact protrusion 131 rotates to contact the charging interface of the power bank, thus achieving charging. Furthermore, a reset member 140 is provided between the rocker 130 and the fixing plate 120. This reset member 140 is compressed and stores elastic potential energy when the device is inserted. When the device is removed, the elastic potential energy is released, causing the rocker 130 to automatically reset, preparing for the next charging operation.

[0044] Of course, the reset element 140 can be an elastic reset element, an active reset element (such as an electric drive rod), or even some buffer damping elements.

[0045] Furthermore, the aforementioned seesaw 130 may have both ends configured to extend beyond the projection area of ​​the fixed plate 120 in the thickness direction of the fixed plate 120, so as to realize the function of rotating from the rear side to the front side or resetting to the rear side of the fixed plate 120 (i.e., ensuring that the fixed plate 120 does not interfere with the movement).

[0046] As mentioned above, the rocker can be configured such that one end portion is initially positioned in front of the fixed plate 120 to facilitate contact with the end face of the device and drive the rocker to rotate. Alternatively, it can be configured as follows: Figures 1-4 The exemplary structure shown only needs to be located on the front side of the fixing plate 120 in the initial state for the end of the device end plate to be used for contacting it. The exemplary structure will be described in detail later and will not be repeated here.

[0047] In different examples, the fixing plate 120 is typically made of metal or high-strength engineering plastic to ensure structural stability and durability. The rocker 130 also uses materials with good mechanical strength and insulation properties, such as nylon reinforced with glass fiber or bakelite, to avoid the risk of short circuits. The charging circuit is integrated at one end of the rocker 130 and can be connected to an external power source via wires. The charging contact protrusion 131 is typically a metal spring pin or charging nail structure to ensure stable electrical contact with the power bank's charging interface. When the reset element 140 is set as an elastic reset element, it can be a stainless steel compression spring or torsion spring; the specific type can be selected according to the structural layout.

[0048] Next Figures 1-4 The structure shown is used as an example for illustration. In the example, the device with a mobile power supply is a railway anti-slip shoe (not shown in the figure), and the mobile power supply inside is connected to a contact charging interface.

[0049] In use, when the user places a device with a power bank into the device in the designated direction, the device will contact the end of the rocker 130 facing the placement direction and apply a pushing force. Since the rocker 130 is hinged to the fixed plate 120 in the middle, the pushing force will cause the rocker 130 to rotate around the pivot 150. This rotational movement causes the charging contact protrusion 131 at the other end to move towards the device, that is, to a position slightly below the upper edge of the fixed plate as shown in the figure, thereby achieving stable contact between the charging contact protrusion 131 and the charging interface of the power bank. The charging circuit is then turned on and charges the power bank. When the device is removed, the pushing force applied to the rocker 130 disappears, the elastic reset member releases the stored elastic potential energy, driving the rocker 130 to rotate in the opposite direction back to the initial position. At the same time, the charging contact protrusion 131 separates from the device, and the charging process stops.

[0050] refer to Figure 2A through hole 121 is provided at the center of the fixing plate 120. One end of the rocker 130 is positioned directly opposite the through hole 121, while the other end extends beyond the edge of the fixing plate 120. Furthermore, the end portion opposite the through hole protrudes to the front of the fixing plate. Thus, when a device with a power supply is placed on the front of the fixing plate 120, the device directly contacts and pushes the exposed end of the rocker 130 through the through hole 121, thereby triggering the rotation of the rocker 130.

[0051] Specifically, the through hole 121 is rectangular, and its size must ensure that the end of the rocker 130 can protrude and be hidden within the through hole 121 without interference. The end of the rocker 130 that extends beyond the fixed plate 120 is usually slightly longer than the other end, so that after rotation it can move to the front of the fixed plate 120 and contact the charging port of the anti-slip shoe for charging.

[0052] like Figure 4 As shown, a fixing seat 122 is also provided on the rear side of the fixing plate 120. The fixing seat 122 is a C-shaped folded plate with a skirt 1221 extending out to fit against the fixing plate 120. The skirt 1221 is fixed to the frame 110 or the fixing plate 120 by screws. In the structure shown in this example, the skirt 1221 is fixed to the fixing plate 120. A rotating shaft 150 is provided through the two plates of the fixing seat 122 perpendicular to the fixing plate 120. The middle part of the rocker 130 is rotatably connected to the rotating shaft 150 by means of bearings or direct sleeve. In this example, it is directly sleeved on the two plates. Thus, the fixing seat 122 and the rotating shaft 150 provide a stable and low-friction rotation fulcrum for the rocker 130, ensuring that the rocker 130 can rotate smoothly under force and reducing jamming.

[0053] A torsion spring is wound around the rotating shaft 150 as a reset element 140. Specifically, the spring coil portion 141 of the torsion spring is directly wound around the rotating shaft 150 of the fixed seat 122, and the two torsion arms 142 extending from the end of the spring coil respectively abut against the end of the rocker plate 130 facing the central hole and a specific part of the fixed seat 122.

[0054] In this example, the torsion spring is made of spring steel, and its inner diameter is tightly fitted with the outer diameter of the rotating shaft 150. The two torsion arms 142 are respectively engaged with the opposing surfaces of the fixed base 122 and the fixed plate 120, as well as the end area of ​​the rocker 130. When the device is placed in and the rocker 130 is rotated, the rocker 130 compresses one of the torsion arms 142 of the torsion spring, allowing the torsion spring to store torque potential energy. When the device is removed, the torsion spring releases the torque, pushing the rocker 130 to rotate in the opposite direction and reset.

[0055] In some examples, seesaw 130, such as Figure 5As shown, the device includes a first plate 132, a second plate 133, a third plate 134, and a fourth plate 135 connected by bending in sequence. The first plate 132 extends flanges on both sides in the thickness direction, and the flanges are rotatably connected to the fixed plate 120 through shaft holes. The second plate 133 and the third plate 134 are bent toward the edge of the fixed plate 120, and the end of the third plate 134 extends to the front side of the fixed plate 120. The fourth plate 135 is connected to the charging circuit and has contact charging protrusions 131. Each plate segment is integrally stamped or injection molded, and the bending angle needs to be optimized to ensure the leverage ratio and movement trajectory. Furthermore, the multi-segment bent plate structure of the rocker 130 forms a double lever structure. When the device pushes the third plate 134, the torque is transmitted through the second plate 133, the first plate 132 acts as a fulcrum, and the fourth plate 135 amplifies the contact displacement. This allows the bending structure to achieve greater displacement output within a limited space, improves the reliability of contact docking, and fully hides and avoids wear when the rocker 130 is not rotated to the front of the fixed plate 120.

[0056] like Figure 2 The end of the rocker 130 facing the direction in which the equipment is placed has an impact protrusion 136 on the side near the fixing plate 120. The protrusion is usually made of rubber or plastic and is fixed to the rocker 130 by bolts. Of course, it can also be fixed to the rocker 130 by adhesive or inserts. The impact protrusion 136 is positioned directly opposite the contact point of the equipment to buffer the impact force and protect the equipment structure.

[0057] Combination Figure 1 In this embodiment, the frame 110 includes support plates 111 disposed on the left and right sides of the fixed plate 120. A placement platform 112 is also disposed between the two support plates 111. The placement platform 112 is opposite to the fixed plate 120, so that the support plates on the left and right sides, the placement platform 112, and the fixed plate 120 define a placement space for placing devices with mobile power supplies. In this way, each anti-slip shoe is placed individually in its corresponding charging space, which can prevent accidental short circuits caused by accidental contact.

[0058] Guide rollers 113 are provided on the two support plates 111 facing the placement space, and an RFID antenna is provided inside the placement platform 112. In this way, the guide rollers 113 on the two support plates 111 facing the placement space can limit the movement of the anti-slip iron shoes when they are placed in the cabinet. The anti-slip iron shoes (or drones or other devices) are equipped with RFID tags. When the anti-slip iron shoes are placed in the cabinet, the RFID antenna recognizes the RFID tags, determines that there is a device at the current location, and then supplies power to that location.

[0059] According to an embodiment of this application, a management cabinet 200 is provided, with reference to... Figure 6 and Figure 7As shown, the device includes a cabinet 210, which houses a charging unit 100 for contact charging of devices with mobile power supplies, as described in the previous embodiment. The cabinet 210 has a door 211 on one side, which allows for the insertion and removal of devices. Figure 7 As shown, the charging unit 100 is inclined inside the cabinet 210, with the side of the charging unit 100 closest to the cabinet door 211 of the cabinet 210 being higher than the other side; in this way, when the user puts a charging device such as anti-slip iron shoes into the charging unit 100, the device will naturally slide along the inclined direction under the action of gravity, and then its end face will be blocked and stop moving after contacting the front side of the fixing plate 120, thus realizing the placement process.

[0060] The above description is merely a preferred embodiment of this utility model. 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. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
