Technical Field
[0001] This utility model relates to the field of card-based power supply technology, and in particular to a card-based power supply structure for room cards. Background Technology
[0002] In accommodation settings such as hotels and apartments, the card-operated power supply system is a key component for ensuring power management. As the accommodation industry develops, people's demands for convenience and intelligence in accommodation are constantly increasing. The card-operated power supply system has gradually transformed from a simple mechanical card to a complex system integrating multiple technologies. From initially simply enabling card insertion for power supply, it now needs to consider multiple aspects such as safety and convenience. The design and technology of this structure have been continuously upgraded, and its performance directly affects the user experience and the management efficiency of the operator.
[0003] Currently, among the common room card power-drawing technologies, one is a non-contact power-drawing structure based on the principle of electromagnetic induction. It uses the induction coil inside the room card to conduct electromagnetic induction with the transmitting coil of the power-drawing device. When the room card is close to the power-drawing device, an induced current is generated, thereby activating the circuit and realizing the power-drawing function. Another type uses a simple mechanical contact structure. After the room card is inserted into the slot, it is directly connected to the circuit through metal contacts to turn on the power. Both of these methods meet the daily use needs to a certain extent and have been widely used in the market.
[0004] However, existing room card power-feeding structures have significant shortcomings, including problems with card fixation and detection stability. Most card-feeding structures rely on a single method of fixing the room card, simply using the friction of the slot. During use, factors such as personnel movement and equipment vibration can easily cause the room card to loosen, leading to poor contact and resulting in power interruption or instability. At the same time, most detection devices are directly exposed to the external environment without effective protection measures, allowing dust, moisture, and other impurities to easily enter, affecting the accuracy of the detection device in identifying the room card and greatly reducing the convenience and reliability of power supply. Therefore, a new room card power-feeding structure is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a card insertion structure for power supply via room card, which aims to improve the problems of unstable room card fixation and inconvenient identification in the prior art.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A card insertion structure for power generation of a room card includes a base plate, a detection box fixedly connected to the side wall of the base plate, an insertion slot provided on the top of the detection box, and a fixing component provided inside the insertion slot. The fixing component is used to fix the room card so that the detection device can identify the room card.
[0008] The fixing assembly includes multiple movable rollers arranged in an array on one side of the inner wall of the insertion slot. Multiple receiving slots are provided on both the left and right sides of the inner wall of the insertion slot. Fixed rollers are rotatably connected to the inner wall of one receiving slot, and a support plate is slidably connected to the inner wall of the receiving slot on the other side. Both ends of the movable rollers are rotatably connected to the inner wall of the support plate. A return spring is provided on the side wall of the support plate. One end of the return spring is fixedly connected to the side wall of the support plate, and the other end of the return spring is fixedly connected to the inner wall of the receiving slot.
[0009] As a further description of the above technical solution:
[0010] An indicator is provided on the outer wall of the detection box, and the side wall of the indicator is fixedly connected to the outer wall of the detection box.
[0011] As a further description of the above technical solution:
[0012] The substrate has a base on its sidewall, and the base sidewall is fixedly connected to the substrate sidewall.
[0013] As a further description of the above technical solution:
[0014] The top of the base is fixedly connected to symmetrical connecting plates, and a connecting shaft is provided between the connecting plates.
[0015] As a further description of the above technical solution:
[0016] Both ends of the connecting shaft are fixedly connected to the side wall of the connecting plate. A connecting seat is rotatably connected to the outer wall of the connecting shaft. A protective cover is fixedly connected to the bottom of the connecting seat. A locking hole is provided at the bottom of the protective cover.
[0017] As a further description of the above technical solution:
[0018] The base is fixedly connected to a fixed seat at its bottom, a movable column is slidably connected to the inner wall of the fixed seat, and a horizontal block is fixedly connected to the top of the movable column.
[0019] As a further description of the above technical solution:
[0020] A movable button is fixedly connected to the bottom of the movable column, and a limiting plate is fixedly connected to the outer wall of the movable column. The limiting plate is slidably connected to the inner wall of the fixed base.
[0021] As a further description of the above technical solution:
[0022] A limiting spring is sleeved on the outer wall of the movable column. The limiting spring is located on the inner wall of the fixed seat. One end of the limiting spring is fixedly connected to the inner wall of the fixed seat, and the other end of the fixed seat is slidably connected to the bottom of the limiting plate.
[0023] This utility model has the following beneficial effects:
[0024] 1. In this utility model, when the room card is inserted into the insertion slot and slides down, one side of the room card presses against the movable roller. The displacement of the movable roller causes the bearing plate to move into the receiving slot. The bearing plate presses against the return spring. Under the cooperation of the movable roller pushed by the return spring and the fixed roller, the room card is fixed in the insertion slot. The detection device detects that the room card has completed power access, achieving the effect of rapid power access operation. This solves the problems of unstable room card fixation and inconvenient identification, and improves the stability and convenience of power access.
[0025] 2. In this utility model, the user rotates the movable knob, which drives the movable column and the limiting plate to rotate. When the angle of the limiting plate is consistent with the locking hole, the user pulls down the movable knob to move the limiting plate and the horizontal block down. After the horizontal block moves out of the locking hole, the protective cover is unlocked, which achieves the effect of quickly unlocking the protective cover. This solves the problem that the traditional card insertion structure has no protective cover, which causes the detection device to be unable to recognize the room card due to dust. This improves the stability of the detection device. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a card insertion structure for power generation from a room card, including a base plate 3. The base plate 3 is made of high-strength engineering plastic material, and its main function is to provide basic support for the entire card insertion structure, connect the various components together, ensure the relative position of each component is fixed, and ensure the stability of the entire structure. A detection box 4 is fixedly connected to the side wall of the base plate 3. The detection box 4 is made of metal material, which can effectively shield external electromagnetic interference and ensure the stable operation of the detection device. An insertion slot 5 is provided on the top of the detection box 4. The function of the insertion slot 5 is to provide a channel for the insertion of the room card. A fixing component is provided inside the insertion slot 5. The fixing component is used to fix the room card so that the detection device can identify the room card.
[0033] The fixing assembly includes multiple movable rollers 7, which are generally made of wear-resistant rubber with a certain degree of friction. Their main function is to provide rolling support when the room card is inserted, guiding the room card to slide down stably. The movable rollers 7 are arranged in an array on one side of the inner wall of the insertion slot 5. Multiple receiving slots 9 are provided on both the left and right sides of the inner wall of the insertion slot 5. The receiving slots 9 provide installation space for the fixed rollers 6 and the support plate 8. Their material is the same as that of the base plate 3. Fixed rollers 6 are rotatably connected to the inner wall of one receiving slot 9. The fixed rollers 6 are made of metal with a smooth surface and play a role in assisting in fixing the position of the room card and guiding the room card to slide down. The support plate 8 is slidably connected to the inner wall of the other receiving slot 9. The support plate 8 is made of lightweight aluminum alloy. It is used to support the movable rollers 7 and to displace them when the room card squeezes the movable rollers 7. The left and right ends of the movable rollers 7 are rotatably connected to the inner wall of the support plate 8. A return spring 10 is provided on the side wall of the support plate 8. Its function is to push the support plate 8 and the movable rollers 7 to return to their original positions after the room card is removed. One end of the return spring 10 is fixedly connected to the side wall of the support plate 8. The other end is fixedly connected to the inner wall of the receiving groove 9. An indicator 21 is provided on the outer wall of the detection box 4. The indicator 21 is made of plastic and is arrow-shaped. It is used to guide the user to insert the room card. The side wall of the indicator 21 is fixedly connected to the outer wall of the detection box 4. A base 1 is provided on the side wall of the base plate 3. The base 1 is made of metal and is used to fix the device to the wall to increase the stability of the entire device. The side wall of the base 1 is fixedly connected to the side wall of the base plate 3. Symmetrical connecting plates 11 are fixedly connected to the top of the base 1. The connecting plates 11 are used to fix the connecting shaft. At position 12, a connecting shaft 12 is provided between the connecting plates 11. Both ends of the connecting shaft 12 are fixedly connected to the side walls of the connecting plates 11. A connecting seat 13 is rotatably connected to the outer wall of the connecting shaft 12. The connecting seat 13 is used to connect the protective cover 2 and the connecting shaft 12. The protective cover 2 is fixedly connected to the bottom of the connecting seat 13. The protective cover 2 is generally made of transparent high-strength plastic, which facilitates observation of the internal situation and also plays a protective role. A locking hole 19 is opened at the bottom of the protective cover 2. The shape of the locking hole 19 is consistent with the cross-section of the transverse block 17 and the movable column 15.
[0034] Specifically, after unlocking, the user can open the protective cover 2, which rotates upwards around the connecting shaft 12. The room card is then inserted into the insertion slot 5. The room card moves downwards along the inner wall of the insertion slot 5, and its left and right outer walls come into contact with the fixed roller 6 and the movable roller 7. The fixed roller 6 rotates at its own axis, and the movable roller 7 also begins to rotate under the frictional force of contact with the room card. Guided by the rolling motion of the fixed roller 6 and the movable roller 7, the room card continues to move downwards stably. Simultaneously, the side wall of the room card presses against multiple movable rollers 7 on one side. After being pressed, the movable rollers 7 move horizontally towards the receiving slot 9. The horizontal position of the movable rollers 7... The movement causes the supporting plate 8 on one side to also move into the receiving groove 9. The supporting plate 8 slides along the inner wall track of the receiving groove 9. The displacement of the supporting plate 8 causes the return spring 10 on its side wall to be compressed. The return spring 10 is compressed and produces elastic deformation. The room card is fixed in the insertion groove 5 by the cooperation of the movable roller 7 pushed by the return spring 10 and the fixed roller 6. At the same time, the detection device inside the detection box 4 detects the room card to complete the power-on operation, thereby achieving the effect of fixing the room card and identifying power. When the power is successfully obtained, the user can close the protective cover 2. The protective cover 2 rotates downward around the connecting shaft 12 to close.
[0035] Reference Figure 3 A fixed base 14 is fixedly connected to the bottom of the base 1. The fixed base 14 is made of the same material as the protective cover 2. Its main function is to provide a stable mounting base for components such as the movable column 15, ensuring that the entire unlocking structure can be firmly connected to the base 1 and maintaining the integrity of the structure. The movable column 15 is slidably connected to the inner wall of the fixed base 14. The movable column 15 plays the role of connecting and transmitting power, transmitting the rotation and displacement of the movable button 18 to the limit plate 16 and the horizontal block 17. The horizontal block 17 is fixedly connected to the top of the movable column 15. The horizontal block 17 is made of hard plastic. Its function is to lock and unlock the protective cover 2 by cooperating with the locking hole 19 through its own displacement during the unlocking process. The movable button 18 is fixedly connected to the bottom of the movable column 15. The surface of the movable button 18 has an anti-slip texture for easy operation. The user controls the operation of the entire unlocking mechanism by rotating and pulling the movable button 18. The outer wall of the movable column 15 is fixedly connected to the limiting plate 16, which is made of a thin metal sheet. Its function is to cooperate with the limiting spring 20 to limit the displacement range of the movable column 15. The limiting plate 16 is slidably connected to the inner wall of the fixed base 14. The outer wall of the movable column 15 is fitted with the limiting spring 20, which provides a reverse elastic force after unlocking, so that the movable column 15 is stuck under the protective cover 2 to prevent the movable column 15 from resetting. The limiting spring 20 is located on the inner wall of the fixed base 14. One end of the limiting spring 20 is fixedly connected to the inner wall of the fixed base 14, and the other end of the fixed base 14 is slidably connected to the bottom of the limiting plate 16.
[0036] Specifically, when using the card-operated power supply structure of this room card, the user first rotates the movable button 18. The user pinches the movable button 18 with their fingers and rotates it clockwise. The rotation of the movable button 18 drives the movable column 15 at its top. Since the movable column 15 is fixedly connected to the movable button 18, the movable column 15 will rotate around its own axis along with the movable button 18. The rotation of the movable column 15 drives the limiting plate 16 to rotate as well. The limiting plate 16 is fixedly connected to the movable column 15, so it will make a circular motion on the inner wall of the fixed base 14. When the rotation angle of the limiting plate 16 is consistent with the position of the locking hole 19, at this time, the position of the limiting plate 16 and the locking hole 19 are on the same plane, and the shape of the limiting plate 16 matches the shape of the locking hole 19. Then the movable button 18 can be pulled down. The user holds the movable button 18 with their fingers and applies a pulling force in a vertically downward direction. The displacement of the movable button 18 causes the limiting plate 16 to rotate. 6 and the transverse block 17 also move accordingly. The displacement of the limiting plate 16 causes the limiting spring 20 to be compressed. When the transverse block 17 moves to the outer wall of the locking hole 19, the transverse block 17 moves out of the locking hole 19 and reaches the outer edge of the locking hole 19. The user rotates the movable knob 18 again, in the opposite direction to the first rotation, so that the transverse block 17 will not be pushed back into the locking hole 19 by the limiting spring 20. At this time, the position of the transverse block 17 is fixed and is no longer affected by the reverse force of the limiting spring 20, thus completing the unlocking of the protective cover 2. This achieves the effect of quickly opening and closing the protective cover 2. When it is necessary to close the protective cover 2, the above steps are reversed. First, align the locking hole 19 of the protective cover 2 with the transverse block 17, and then rotate the movable knob 18 to align the transverse block 17 with the locking hole 19. Under the elastic force of the limiting spring 20, the transverse block 17 enters the locking hole 19 to achieve locking.
[0037] Working Principle: When using the card-operated power supply structure, the user first rotates the movable button 18. The rotation of the movable button 18 drives the movable column 15 at its top, which in turn rotates the limiting plate 16. When the limiting plate 16 rotates to the same angle as the locking hole 19, the user can pull down the movable button 18. The displacement of the movable button 18 causes the limiting plate 16 and the horizontal block 17 to also move. The displacement of the limiting plate 16 compresses the limiting spring 20. When the horizontal block 17 moves to the outer wall of the locking hole 19, the user rotates the movable button 18 again, preventing the horizontal block 17 from being pushed back into the locking hole 19 by the limiting spring 20. This unlocks the protective cover 2, achieving the effect of quickly opening and closing the protective cover 2. After unlocking, the user can open the protective cover. 2. Insert the room card into the insertion slot 5. As the room card moves downward along the inner wall of the insertion slot 5, its left and right outer walls will contact the fixed roller 6 and the movable roller 7. Under the rolling guidance of the fixed roller 6 and the movable roller 7, the room card continues to move downward steadily. At the same time, the side wall of the room card also squeezes multiple movable rollers 7 on one side. The horizontal displacement of the movable roller 7 will drive the bearing plate 8 on one side to move into the receiving slot 9. The displacement of the bearing plate 8 causes the return spring 10 on its side wall to be compressed. The room card is then fixed inside the insertion slot 5 by the movable roller 7 pushed by the return spring 10 and the fixed roller 6. At the same time, the detection device inside the detection box 4 detects the room card to complete the power-on operation, thereby achieving the effect of fixing the room card and identifying power. After the power is successfully obtained, the user can close the protective cover 2.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
