DETAILED DESCRIPTION

[0039] In order to make the technical problems solved by the utility model, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the utility model are further described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0040] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0042] From the background technology, we can know that with the development of science and technology, the current door products can expand the functions of the products by adding electronic devices such as smart locks, electronic cat eyes, wireless doorbells, anti-theft devices, remote control devices, etc., so as to improve the user experience of the products.

[0043] In addition to the above-mentioned method of adding electronic products to door products, the existing technology can also directly use smart doors to meet the above needs. Smart doors are doors with intelligent functions. They usually integrate modern technologies such as sensors, automatic control, artificial intelligence, etc. to provide a more convenient, safe and intelligent entry and exit experience. Smart doors have a variety of functions and applications, such as:

[0044] Intelligent identification: Smart doors can authenticate personnel through fingerprint recognition, facial recognition, iris recognition, voiceprint recognition and other technologies (including but not limited to smart locks, electronic cat eyes, etc.);

[0045] Alarm and anti-theft: If someone breaks in forcibly or stays at the door for a long time, the smart door can automatically sound an alarm and inform the user through the preset terminal;

[0046] Monitoring: Remote monitoring and recording inside and outside the smart door room can be achieved through cameras or connection with smart home systems.

[0047] The above-mentioned electronic devices used in door products basically all have power supply requirements. Due to the particularity of the door product structure, the power of the electronic devices can generally only be provided by batteries. However, since the battery capacity is limited by the battery life, the battery life performance of the electronic devices located on the door is relatively poor. Users need to charge the electronic devices on the door or replace the batteries regularly, and the cost of use is relatively high. The high frequency of charging and battery replacement also reduces the user experience.

[0048] To this end, this embodiment provides a power generation device, which is used for door leaves. The power generation device powers electronic devices located on the door leaves through the opening and closing movement of the door leaves, thereby solving a series of technical problems caused by the poor battery life performance of the corresponding electronic devices.

[0049] Please refer to the attached Figure 2-Figure 5 The power generation device includes a moving component 10 and a power generation module 20. The power generation device achieves the purpose of generating electrical energy by the power generation module 20 through the relative movement of the moving component 10 and the power generation module 20.

[0050] Taking the application scenario of the power generation device on the door leaf 90 as an example, the moving component 10 is used to be movably installed on the door leaf 90. In this matching mode, the moving component 10 is configured so that during the opening and closing movement of the door leaf 90 where the moving component 10 is located, the moving component 10 moves to generate kinetic energy. The movement mode can be directly driven by the door leaf 90, or it can be driven by an external force (such as friction generated with the ground) during the movement of the door leaf 90.

[0051] It needs to be explained that, in the above-mentioned embodiment, the opening and closing movement of the door leaf 90 refers to the mechanical movement performed by the door during the opening and closing process. Specifically, the opening and closing movement of the door leaf 90 includes an opening movement and a closing movement in opposite directions. When the door leaf 90 performs the opening and closing movement, its movement mode can be a rotational movement, a translational movement, or a combination of rotational and translational movement. For example, the door leaf 90 can be configured to rotate counterclockwise around the hinge about the rotating shaft, or to reciprocate translationally along the guide rail. Of course, when the door leaf 90 is configured as a folding door, adjacent door leaves 90 can rotate counterclockwise around their respective rotating shafts during the translational movement along the guide rail, and fold or unfold.

[0052] It should also be noted that the opening and closing movement of the door leaf 90 can be generated by an external force, such as the force applied by a user when pushing or pulling the door, or it can be generated by a driving device installed on the door leaf 90, such as using a motor to drive the door leaf 90 to rotate or move.

[0053] It should be understood that the moving component 10 can be directly and movably installed on the door leaf 90, or it can be movably installed on the supporting base of the power generation device and then further installed on the door leaf 90 through the supporting base of the power generation device. This embodiment is not strictly limited here.

[0054] During the opening and closing movement of the door leaf 90, the movement of the moving component 10 relative to the door leaf 90 mainly depends on the connection between the moving component 10 and the door leaf 90. In one embodiment, the moving component 10 and the door leaf 90 may be directly or indirectly connected in rotation, wherein the rotation connection includes direct or indirect connection through a rotating pair, or a rolling connection, or a composite connection of rotation and movement, or other connection methods that can cause rotation. In other embodiments, the moving component 10 and the door leaf 90 may also be connected in a moving manner, that is, during the opening and closing movement of the door leaf 90, the moving component 10 can generate relative movement with the door leaf 90, including but not limited to translational movement, lifting movement, etc.

[0055] The power generation module 20 is transmission-connected to the moving part 10. When the power generation device is applied to the door leaf 90, the power generation module 20 can be fixedly mounted on the door leaf 90 and electrically connected to the electronic equipment on the door leaf 90, so that the moving part 10 drives the power generation module 20 to move when generating kinetic energy during movement. In the process of generating a transmission relationship between the moving part 10 and the power generation module 20, the kinetic energy generated by the moving part 10 can drive the power generation module 20 to generate electricity, thereby realizing the conversion of kinetic energy into electrical energy, and allowing the power generation module 20 to power the electronic equipment on the door leaf 90.

[0056] It needs to be explained that the power generation module 20 provided in this embodiment is a device that can convert mechanical energy into electrical energy. Generally, the power generation device is composed of a power machine and a generator 21. The moving component 10 is connected to the power mechanical part in the power generation device through a transmission, so that when the door leaf 90 opens and closes, the moving component 10 utilizes the mechanical energy of its relative movement to establish a transmission relationship with the power mechanical part, and finally drives the movement of the generator 21 to generate electrical energy.

[0057] In one embodiment, the generator 21 in the power generation module 20 can be an electromagnetic induction generator 21, a piezoelectric ceramic generator 21, a three-phase AC motor, or other generators 21 that can be implemented by technicians in this field, as well as a device module that can generate electrical energy when driven by an external force.

[0058] In addition to rotational power generation, the power generation mode of the power generation device can also be friction power generation, vibration power generation, electromagnetic induction power generation, and other power generation devices that use mechanical energy to convert into electrical energy.

[0059] The power generation device is provided with a moving part 10 and a power generation module 20 that can move relatively, so that the moving part 10 can drive the power generation module to generate electricity during the movement. The structure is simple and reliable, and the cost is low, which is conducive to the wide application of doors.

[0060] When the power generation device is used in the door, the user can use the process of opening and / or closing the door to drive the power generation module 20 through the mechanical energy of the moving part 10 to generate electricity, thereby powering the electronic equipment on the door. This process is not only energy-saving and environmentally friendly, but also achieves the purpose of extending the user's charging or battery replacement cycle for electronic devices, reducing the user's charging and battery replacement operations on electronic devices, improving user experience, and extending the service life and life of the door.

[0061] It can be seen from the above embodiment that the moving component 10 drives the power generation module 20 to generate electrical energy by establishing a transmission relationship with the power generation module 20, and the movement mode of the moving component 10 and the way the power generation module 20 generates electrical energy determine the transmission connection relationship between the moving component 10 and the power generation module 20. For example, in the case where the movement mode of the moving part 10 is rotational motion relative to the door leaf 90 and the power generation module 20, and the power generation module 20 also generates electrical energy by means of rotational motion of its power mechanical part, the moving part 10 can directly serve as the power mechanical part of the power generation module 20, and directly drive the generator 21 of the power generation module 20 through the moving part 10, or it can form a transmission connection relationship with the power mechanical part of the power generation module 20 through the transmission mechanism 30; for another example, in the case where the movement mode of the moving part 10 is movement relative to the door leaf 90 and the power generation module 20, and the power generation module 20 generates electrical energy by means of rotational motion of its power mechanical part, a winding wheel can be set between the power mechanical part of the power generation module 20 and the moving part 10, so that the moving part 10 pulls the winding wheel by winding a rope during the movement, so as to achieve the purpose of driving the power mechanical part of the power generation module 20.

[0062] Therefore, it can be understood that the efficiency of the power generation module 20 in generating electricity depends largely on the movement efficiency of the moving component 10 during the opening and closing movement of the door leaf 90, as well as the transmission ratio between the moving component 10 and the power mechanical part of the power generation module 20.

[0063] In one embodiment, please continue to refer to the attached Figure 2-Figure 5 The moving part 10 and the power generation module 20 are connected by a transmission mechanism 30, so that the transmission relationship between the power generation module 20 and the moving part 10 is more stable. In one embodiment, the transmission mechanism 30 can be used to generate a speed difference between the moving part 10 and the power generation module 20, and specifically, the movement speed of the power generation module 20 can be greater than the movement speed of the moving part 10, so as to achieve the purpose of improving the power generation efficiency of the power generation module 20, so that when the power generation device is applied to the door leaf 90, the door leaf 90 provides more power for the electronic equipment on the door leaf 90 under the conditions of the same opening and closing movement speed and the same opening and closing movement stroke, effectively enhancing the endurance performance of the electronic equipment on the door leaf 90, and further reducing the frequency of users replacing or charging the batteries of the electronic equipment.

[0064] It is understandable that the transmission mode of the transmission mechanism 30 depends on the movement mode of the moving component 10 and the power generation mode of the power generation module 20. There are many ways for the two to achieve the above effects, such as:

[0065] 1. By using a transmission wheel set as the transmission mechanism 30 of this embodiment, the transmission ratio between the moving component 10 and the power generation module 20 can be changed by changing the diameters of the driving wheel and the driven wheel in the transmission wheel set;

[0066] 2. By using a gear set as the transmission mechanism 30 of this embodiment, the transmission ratio between the moving component 10 and the power generation module 20 can be changed by changing the number of teeth of the driving gear and the driven gear;

[0067] 3. Using a planetary gear train as the transmission mechanism 30 of this embodiment;

[0068] 4. A worm gear mechanism is used as the transmission mechanism 30 of this embodiment;

[0069] 5. A chain or belt drive is used as the transmission mechanism 30 of this embodiment.

[0070] Please refer to the attached Figure 2-Figure 5 In this embodiment, a roller is used as the moving part 10 of the power generation device. The roller is used to be movably installed on the door leaf 90 in the direct or indirect manner as described above, and when the roller is installed on the door leaf 90, it rotates to generate kinetic energy during the opening and closing movement of the door leaf 90.

[0071] The roller can better form a good contact relationship with the ground, guide rails and other surfaces used to provide the roller rotation position, which can effectively improve the movement efficiency of the moving component 10 during the opening and closing movement of the door leaf 90, and make the transmission efficiency between it and the power generation module 20 higher, ultimately making the power generation module 20 more efficient in generating electricity.

[0072] It can be understood that the roller can be set at the upper edge or lower edge of the door leaf 90 according to the movement mode of the door leaf 90 used by the power generation device, and the rotation axis of the roller can also be set to be parallel to the thickness direction of the door leaf 90 according to the opening and closing mode of the door leaf 90, or to be perpendicular to the thickness direction of the door leaf 90, so that the roller as the moving part 10 can be suitable for door leaves 90 with different opening and closing modes such as rotating opening and closing or moving opening and closing.

[0073] Continuing with the above embodiment, Figure 2-Figure 5As shown, the power generation module 20 includes a generator 21 and a circuit board 22. According to the above embodiment, it can be understood that the generator 21 can adopt any type of generator 21, motor and device module that generates electric energy under the drive of external force as mentioned above. The generator 21 is connected to the moving part 10 through transmission to achieve the purpose of generating electric energy during the movement of the moving part 10. The circuit board 22 is electrically connected to the generator 21. At least one power supply interface 23 is provided on the circuit board 22. The power supply interface 23 can be set as a USB interface in this embodiment. The power supply interface 23 is used to connect to the electronic equipment on the door leaf 90. The circuit board 22 can be provided with a charging circuit so that when the generator 21 generates electric energy, the electric energy is transferred to the power supply interface 23 through the charging circuit and the purpose of powering the electronic equipment on the door leaf 90 is achieved.

[0074] In one embodiment, taking the generator 21 as a three-phase AC motor as an example, the three-phase AC motor can generate electrical energy during both forward rotation and reversal, that is, in an implementation using a roller as the moving component 10, regardless of whether the door leaf 90 is in the opening process or the closing process (during the forward and reverse rotation of the roller), the moving component 10 can drive the three-phase AC motor to generate electrical energy. Figure 6 This is a circuit structure diagram on the circuit board 22 of the utility model, wherein a rectifier bridge 221 and a voltage stabilizing element 222 are provided on the circuit board 22, the output end of the three-phase AC motor is connected to the input end of the rectifier bridge 221, the output end of the rectifier bridge 221 is connected to the input end of the voltage stabilizing element 222, and the output end of the voltage stabilizing element 222 is connected to the load (the electronic device of the door leaf 90), so that when the electric energy generated by the generator 21 is AC, the AC power is converted into DC power and the voltage of the current output by the power supply interface 23 is stabilized.

[0075] On the basis of increasing the transmission ratio of the moving part 10 and the power generation module 20 through the transmission mechanism 30, in order to further improve the force transmission efficiency between the moving part 10 and the power generation module 20, the transmission mechanism 30 arranged between the moving part 10 and the power generation module 20 is set as a gear set. In order to achieve the purpose of increasing the transmission ratio between the two to a minimum, the transmission mechanism 30 includes a first gear 31 and a second gear 32. The first gear 31 is coaxially arranged with the roller, and the second gear 32 is coaxially arranged on the shaft of the generator 21. The roller and the generator 21 are connected by the first gear 31 and the second gear 32. In this embodiment, in order to achieve the purpose of the rotation speed of the shaft of the generator 21 being greater than the rotation speed of the roller, the transmission ratio between the moving part 10 and the generator 21 can be increased by setting the number of teeth of the first gear 31 to be greater than the number of teeth of the second gear 32, so that the roller rotates at the same number of turns (when the opening and closing movement stroke of the door leaf 90 is consistent), and the power mechanical part of the generator 21 can rotate more times, thereby improving the power generation efficiency of the generator 21.

[0076] It should be noted that, when the above-mentioned transmission mechanism 30 adopts a gear set, in addition to the first gear 31 and the second gear 32, more gears can be set according to factors such as the setting spacing between the power generation module 20 and the roller and the overall structure of the power generation device. The present embodiment does not strictly limit the further detailed structure of the transmission mechanism 30, and it only needs to satisfy the transmission connection between the roller and the generator 21 and allow the roller and the generator 21 to have a larger transmission ratio.

[0077] Please continue to refer to the attached Figure 4-Figure 5 , illustratively, a first transmission gear 33 and a second transmission gear 34 are further arranged between the first gear 31 and the second gear 32, and the first gear 31 drives the second gear 32 to rotate through the first transmission gear 33 and the second transmission gear 34. It should be noted here that the first transmission gear 33 and the second transmission gear 34 include at least one toothed disc, and in the case where at least one of the first transmission gear 33 and the second transmission gear 34 includes a plurality of toothed discs, each toothed disc can be coaxially arranged to form a whole. For example, in this example, the second transmission gear 34 includes two coaxially arranged toothed discs, and the first gear 31, the first transmission gear 33, the second transmission gear 34 and the second gear 32 are meshed in sequence, so that when the first gear 31 rotates with the roller, the second gear 32 can also drive the generator 21 to rotate to achieve power generation, and in this embodiment, the rotation speed of the generator 21 shaft can also be greater than the rotation speed of the roller by changing the transmission ratio between the gears.

[0078] In the embodiment where the second transmission gear 34 includes two sprockets arranged side by side, the first transmission gear can mesh with one of the sprockets, and the other sprocket meshes with the second gear 32 to achieve transmission between the gears.

[0079] By adding a first transmission gear 33 and a second transmission gear 34 between the first gear 31 and the second gear 32, the gap between the roller and the generator 21 in the height direction of the device can be compensated, ensuring the stability of the transmission between the two. At the same time, by setting the transmission gear to multiple toothed discs, the gap between the generator 21 and the roller in the thickness direction of the device can be compensated, thereby improving the compactness of the device structure.

[0080] In summary, the structural form of the power generation device provided above can greatly improve the power generation efficiency of the power generation module 20, so as to solve the problem that the electronic equipment located on the door leaf 90 has poor endurance performance, resulting in customers' frequent operation of the corresponding electronic equipment, thereby achieving the purpose of improving the user experience to a certain extent.

[0081] Based on any of the above implementations, please refer to the attached Figure 2-Figure 5 The power generation device also includes a first shell 40. The first shell 40 can be used as a supporting base for the power generation device in this embodiment. A hollow first receiving chamber 41 is formed inside the first shell. The moving component 10 and the power generation module 20 are both installed in the first receiving chamber 41. The various mechanism components are uniformly stored and installed to improve the compactness of the structure and the rationality of the layout of the power generation device, which is convenient for the early production and assembly of the power generation device and the subsequent inspection and maintenance.

[0082] Furthermore, a first opening 42 connected to the first accommodating cavity 41 is provided on one side of the first shell 40, and the moving component 10 at least partially extends out of the first shell 40 through the first opening 42, so that the moving component 10 can normally form a contact relationship with the surface outside the power generation device, for example, by extending out of the first opening 42 and contacting the ground, track, wall, ceiling and other surfaces, it is ensured that when the door leaf 90 is in use, the moving component 10 can generate corresponding movement during the opening and closing movement of the door leaf 90 and drive the power generation module 20 to generate electrical energy.

[0083] In one embodiment, in order to improve the structural stability of the moving component 10 and the power generation module 20 in the first housing 40, the moving component 10 and the power generation module 20 can be assembled in the first receiving cavity 41 through a supporting structure, such as Figure 2-Figure 5As shown, in an embodiment where the moving component 10 is a roller, the roller can be rotatably mounted in the first receiving cavity 41 via the first rotating shaft 11, and the cavity wall of the first receiving cavity 41 is provided with a shaft sleeve corresponding to the end of the first rotating shaft 11, and the power generation module 20 (including the generator 21 and the circuit board 22) is mounted in the first receiving cavity 41 via the support frame 80, wherein the outer shell of the generator 21 is fixedly connected to the support frame 80, and the rotating shaft of the generator 21 is configured to be rotatable relative to the support frame 80.

[0084] Furthermore, in an embodiment where a gear set is used as a transmission mechanism 30 between the power generation module 20 and the roller, each gear structure included in the transmission mechanism 30 can be rotatably arranged between the above-mentioned support frame 80 and the cavity wall of the first accommodating cavity 41 through a gear shaft.

[0085] Continuing with the above implementation, please continue to refer to the attached Figure 2-Figure 5 The power generation device also includes a second shell 50. In this embodiment, the second shell 50 serves as a supporting base for the entire power generation device, and a hollow second receiving cavity 51 is formed therein. A second opening 52 connected to the second receiving cavity 51 is opened on one side of the second shell 50. The first shell 40 is movably arranged in the second receiving cavity 51 and can move relative to the second shell 50 in a direction approaching and away from the second opening 52. The second opening 52 is arranged opposite to the first opening 42, so that the moving component 10 can extend out of the second shell 50 through the second opening 52, thereby ensuring that the moving component 10 can generate relative movement with the opening and closing movement of the door leaf 90 when the power generation device is applied to the door leaf 90.

[0086] According to the above embodiment, the size of the second receiving cavity 51 needs to be set to be able to accommodate the first shell 40, and it is also necessary to provide the first shell 40 with the freedom to move in the second receiving cavity 51 in the direction close to and away from the second opening 52. On this basis, the size of the second opening 52 can be set to be larger than the moving part 10 and smaller than the first shell 40, thereby ensuring that the moving part 10 can extend through the first opening 42 and the second opening 52 and be exposed to the outside of the entire power generation device, while the edge of the second opening 52 forms a certain limiting effect on the first opening 42 to prevent the first shell 40 from detaching from the second shell 50 through the second opening 52.

[0087] In the above, an embodiment in which the power generation device is applied to the door leaf 90, and the moving component 10 contacts the supporting surface such as the ground or the guide rail at the lower edge of the door leaf 90 when the power generation device is in use is taken as an example. When the first housing 40 is located in the second receiving cavity 51 and is close to the second opening 52, the moving component 10 contacts the supporting surface, so that when the door leaf 90 opens and closes, the moving component 10 can generate friction with the supporting surface and move relative to the door leaf 90 and the power generation module 20; when the first housing 40 is located in the second receiving cavity 51 and is far away from the second opening 52, the moving component 10 is separated from the supporting surface, so that when the door leaf 90 opens and closes, the moving component 10 will not generate relative movement with the door leaf 90 and the power generation module 20 due to the movement of the door leaf 90. Of course, the premise of the above example is that the supporting surface is a plane, and the first housing 40 can adjust the distance between the moving component 10 and the supporting surface and the interaction force in the contact state through its relative movement in the second receiving cavity 51.

[0088] Continuing with the above embodiment, the power generation device further includes an elastic component 60 , which is disposed between the first housing 40 and the second housing 50 , and is used to continuously apply an elastic force to the first housing 40 toward the second opening 52 .

[0089] The elastic component 60 described in the above embodiment can be but is not limited to a compression spring, a tension spring, a torsion spring or other components with elastic reset capability. That is to say, the elastic component 60 can also be other components or materials with certain elastic reset capability other than a spring, such as silicone, rubber, foam, leather, etc.

[0090] Specifically, the elastic component 60 can be arranged in the second accommodating cavity 51 and located in the gap between the outer wall of the first shell 40 and the inner wall of the second shell 50. The power generating device is provided with the elastic component 60 to ensure that the moving component 10 can maintain a stable fit with the supporting surface when the power generating device is in use. At the same time, the moving component 10 also has a certain buffering and shock absorbing function to avoid the presence of foreign matter on the supporting surface causing damage to the moving component 10 or even the power generating device.

[0091] Please continue to refer to the attached Figure 2-Figure 5 In the above-mentioned embodiment in which the main body of the power generation device is supported by the first housing 40 and the second housing 50 respectively, a limiting structure 70 is arranged between the first housing 40 and the second housing 50, and the limiting structure 70 has a restrained state and a released state. When the limiting structure 70 is in the restrained state, the limiting structure 70 restrains the first housing 40 at a position relatively far away from the second opening 52; when the limiting structure 70 is in the released state, the first housing 40 has the freedom to move in the direction of approaching and moving away from the second opening 52.

[0092] The second shell 50 limits the first shell 40 to a position relatively far away from the second opening 52 in the second accommodating cavity 51 through the limiting structure 70, so as to prevent the moving component 10 from contacting the supporting surface under the action of the elastic component 60, that is, the moving component 10 can be in a state where most of it is blocked by the second shell 50, which is beneficial to the assembly and transportation of the power generation device.

[0093] Please refer to the attached Figure 2-Figure 5 As a specific embodiment of the limiting structure 70, the limiting structure 70 includes a limiting rib 71 convexly provided on the outer surface of the first shell, and a limiting hole 53 communicating with the second receiving cavity 51 is penetrated on the side wall of the second shell. The limiting hole 53 allows a limiting component such as a limiting screw 72 to at least partially penetrate into the second receiving cavity 51 from the outside of the second shell 50, and the limiting rib 71 can be blocked after passing through the limiting hole 53 and into the second receiving cavity 51. In this way, when the first shell 40 is located in the second receiving cavity 51 and is relatively far away from the second opening 52, the limiting rib 71 is located on the side of the limiting hole 53 away from the second opening 52. At this time, if the limiting screw 72 is inserted into the second receiving cavity 51 through the limiting hole 53, the limiting rib 71 can be blocked, thereby achieving the purpose of limiting the first shell 40 from being reset to a position close to the second opening 52.

[0094] Furthermore, in order to improve the stability of the limiting structure 70 in the constrained state, a groove is provided on the side of the limiting rib 71 close to the second opening 52, which is away from the second opening 52. When the limiting screw restricts the limiting rib 71, the limiting screw can be stuck in the groove, reducing the relative movement between the limiting rib 71 and the limiting screw.

[0095] Of course, in other embodiments, the limiting structure 70 may also be formed by a detachable structure such as a snap structure, a wedging structure, etc.

[0096] This embodiment also provides a door, such as Figure 1 As shown, the door includes a door leaf 90 as described in the above embodiments and a power generation device as described in any of the above embodiments, wherein an electronic device is provided on the door leaf 90, and the power generation device is electrically connected to the electronic device through its power generation module 20.

[0097] In one embodiment, a door suction component 100 is provided on the side of the power generation device facing away from the door leaf 90 , so that the door leaf 90 can be adsorbed at a corresponding position along with the power generation device by the door suction component 100 to keep the door leaf 90 stable.

[0098] To sum up, the door applies a power generation device to the door leaf 90, and utilizes the movement of the door leaf 90 to enable the power generation device to generate electricity, thereby providing electricity for the electronic equipment on the door leaf 90, thereby extending the battery life of the door and reducing the frequency of a series of operations such as battery replacement and charging by the user. It can effectively improve the user experience while also protecting the door to a certain extent.
