[0002] Smart locks are intelligent devices that can be remotely controlled and managed through wireless communication technology, and are usually used for door locks or cabinet locks. Smart locks can be unlocked through mobile phone apps, fingerprint recognition, password input, card swiping, etc., providing a more convenient and secure access control management solution.

[0003] Smart locks are usually powered by batteries, which need to be replaced or charged regularly. You can charge by connecting the charging cable to the charging port of the smart lock, and then plugging the charging cable into a power outlet. The smart lock usually displays the charging status when charging. After charging is complete, you can unplug the charging cable and start using it normally. The charging time and frequency will vary depending on the usage of the smart lock and the battery capacity. In addition, this charging method requires regular observation of the remaining battery power and timely charging.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example 1

[0020] refer to Figures 1 to 5 A wireless power supply unit includes a control unit (not shown in the figure), a power supply module 121, a photovoltaic component 122, and a light source component 3. The control unit and the power supply module 121 are located in an external lock body, the photovoltaic component 122 is located on the external lock body, the power supply module 121 is electrically connected to the photovoltaic component 122, the light source component 3 is installed on a wall close to the photovoltaic component 122, and the light source component 3 and the photovoltaic component 122 are linked through the control unit; when the control unit detects that the power supply module 121 is insufficient in power, the light source component 3 provides a light source for the photovoltaic component 122, and the light source component 3 is connected to the mains.

[0021] Under this design, the operator installs the light source assembly 3 on a wall near the photovoltaic assembly 122. When the control unit in the external lock body detects that the power supply module 121 is low on power, the control unit controls the light source assembly 3 to turn on, and the light source assembly 3 focuses the light source on the photovoltaic assembly 122. The photovoltaic assembly 122 converts the light energy provided by the light source assembly 3 into electrical energy, and then stores it in the power supply module 121 to achieve charging; when the control unit detects that the power supply module 121 has been charged to a preset value, the control unit controls the light source assembly 3 to turn off. Charging in this way does not require connecting a charging cable or replacing batteries, which is very convenient and also avoids the situation where the photovoltaic assembly 122 cannot be charged due to insufficient natural light.

[0022] It should also be noted that the light source assembly 3 is connected to the mains to ensure that the power supply module 121 can be started normally even when the power is insufficient.

[0023] A smart lock comprises a lock body 1, wherein the lock body is mounted on a door body 2, and the lock body 1 is provided with a control unit, a power supply module 121, and a photovoltaic component 3 as described above.

[0024] After the control unit, the power supply module 121 and the photovoltaic assembly 3 are arranged on the lock body 1 of the smart lock, the smart lock does not need to be connected to a charging cable for charging, nor does it need to replace the battery.

[0025] In this embodiment, the lock body 1 includes a door lock front panel 11 and a door lock rear panel 12, and the door lock front panel 11 and the door lock rear panel 12 are respectively installed on the front and back of the door body 2;

[0026] Then the photovoltaic assembly 122 can be installed on the door lock front panel 11 or the door lock rear panel 12, that is, when the light source assembly 3 is located on a wall near the front of the door body 2, the photovoltaic assembly 122 and the power supply module 121 are both located on the door lock front panel 11; when the light source assembly 3 is located on a wall near the back of the door body 2, the photovoltaic assembly 122 and the power supply module 121 are both located on the door lock rear panel 12. It should be noted here that the light source assembly 3 needs to be installed on a wall near the photovoltaic assembly 122 to ensure that the light source assembly 3 can accurately illuminate the photovoltaic assembly 122.

[0027] Preferably, the door lock front panel 11 is an outdoor panel, the door lock rear panel 12 is an indoor panel, the photovoltaic component 122 and the power supply module 121 are both located on the door lock rear panel 12, and the light source component 3 is located on a wall indoors.

[0028] Specifically, the installation position of the photovoltaic component 122 is generally located indoors, that is, on the rear panel 12 of the door lock. We found that if the photovoltaic component 122 is installed outdoors, in the absence of the light source component 3, although the natural light will be more sufficient than indoors, the photovoltaic component 122 often cannot perform energy conversion normally. In the presence of the light source component 3, the light source component 3 will attract many phototropic insects, causing the light source component 3 to be blocked, so it needs frequent maintenance when installed outdoors; therefore, we choose to install both the photovoltaic component 122 and the light source component 3 indoors. Although the natural light source in the room cannot meet the energy conversion of the photovoltaic component 122 in many cases, the light source component 3 will not attract phototropic insects, and the light source component 3 can be connected to the indoor power supply to avoid the light source component 3 increasing the burden on the power supply module 121.

[0029] Furthermore, the light source assembly 3 is located on the wall at the top of the room or on the wall where the door body 2 is located. Of course, the light source assembly 3 can also be installed on the walls on both sides of the door body 2 in the room, but considering that most rooms have entrance corridors, installing it on the wall at the top of the room or on the wall where the door body 2 is located can effectively hide the light source assembly 3 and avoid occupying the width of the corridor.

[0030] Optionally, the light source component 3 is a spotlight. A spotlight is a lighting device that is usually used to focus light and provide high brightness, local lighting or lighting in a specific direction. It can provide a light source for the photovoltaic component 122. Of course, the light source component 3 is not limited to using a spotlight, and other lighting devices that provide a light source for the photovoltaic component 122 can be used.

[0031] In this embodiment, the photovoltaic assembly 122 includes a photovoltaic panel 1221 and a voltage stabilizing module (not shown in the figure). The photovoltaic panel 1221 is located on the top of the door lock rear panel 12, and the voltage stabilizing module is located inside the door lock rear panel 12. The photovoltaic panel 1221, the voltage stabilizing module, and the power supply module 121 are electrically connected in sequence. When the control unit detects that the power supply module 121 is low on power, the light source assembly 3 provides a light source for the photovoltaic panel 1221. The photovoltaic panel 1221 is used to convert light energy into electrical energy, and store it in the power supply module 121 after passing through the voltage stabilizing module.

[0032] In actual operation, when the photovoltaic panel 1221 converts light energy into current, the generated voltage and current may fluctuate due to factors such as light intensity and temperature. Such fluctuations will lead to instability in the output voltage and current, which is not suitable for direct supply to the power supply module. By setting a voltage stabilizing module, the output voltage can be adjusted and stabilized to ensure stable voltage output. The power supply module 121 supplies stable electrical energy to other functions of the smart lock.

[0033] In this embodiment, the voltage stabilizing module is a DC-DC regulator; the power supply module 121 is a capacitor. The DC-DC regulator has the advantages of stable voltage, high efficiency, strong adaptability, small size, fast response speed and high reliability. The power supply module 121 adopts a capacitor, preferably a supercapacitor. As a type of capacitor, the supercapacitor has high energy density and high power density, can store a large amount of charge and realize rapid charging and discharging. Secondly, the supercapacitor has a long life and good cycle stability, and can perform more than hundreds of thousands of charge and discharge cycles. Furthermore, the supercapacitor has good temperature stability and environmental protection characteristics, does not contain harmful substances, and is environmentally friendly.

[0034] Preferably, the door lock front panel 11 is provided with a camera module 111, and the door lock rear panel 12 is provided with a display module 123 electrically connected to the camera module 111, and the camera module 111 and the display module 123 are both electrically connected to the capacitor. The camera module 111 and the display module 123 cooperate to form an electronic cat's eye effect, and the camera module 111 can transmit the outdoor picture to the indoor display module 123, and the user can observe the outdoor situation through the indoor display module 123.

[0035] Preferably, the door lock front panel 11 and the door lock rear panel 12 are respectively provided with a front handle 112 and a rear handle 124. During use, the front handle 112 and the rear handle 124 can facilitate the user to swing the door body 2.

[0036] In addition to opening the smart lock with a traditional key, in this embodiment, a digital panel module 113 is also provided on the door lock front panel 11, and the digital panel module 113 is electrically connected to the capacitor. The user can also set an opening password through the digital panel module 113 and open the smart lock by entering the password.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements or modifications without departing from the principle of the present invention. These improvements or modifications should also be regarded as within the protection scope of the present invention.
