Description

Technical Field

[0001] This utility model belongs to the field of wireless charging technology, and in particular relates to a door lock with a wireless charging device. Background Technology

[0002] A photovoltaic cell is a semiconductor device that directly converts light energy into electrical energy. When an energy storage device connected to the photovoltaic cell needs charging, light emitted from the transmitter illuminates the photovoltaic cell. Upon receiving the light, the photovoltaic cell converts the light energy into electrical energy to charge the energy storage device. Since the photovoltaic cell requires light from the transmitter for charging, the transmitter and the photovoltaic cell need to be aligned to improve charging efficiency. However, existing technologies suffer from inconvenient alignment between the transmitter and the photovoltaic cell. Utility Model Content

[0003] The purpose of this utility model is to provide a wireless charging device and a door lock, which aims to solve the technical problem of inconvenient alignment between the transmitter and receiver in existing wireless charging devices.

[0004] This invention is implemented as follows: Firstly, a wireless charging device is provided, comprising a transmitter and a receiver. The receiver includes a photovoltaic cell, and the transmitter includes a main housing, a visible light beam emitting part, a charging light beam emitting part, and an angle adjustment component. Both the visible light beam emitting part and the charging light beam emitting part are disposed on the main housing. The angle adjustment component is used to adjust the emission angle of the visible light beam emitting part and the charging light beam emitting part. The visible light beam emitting part is used to form a visible light spot, and the charging light beam emitting part is used to form a charging light spot. The visible light spot is used to indicate the position of the charging light spot.

[0005] By mounting both the visible beam emitter and the charging beam emitter on the main housing, and connecting the receiver to the power supply device, the charging beam emitted by the charging beam emitter illuminates the photovoltaic cell during charging. The photovoltaic cell then converts the energy carried in the charging beam into electrical energy. Compared to existing technologies, the main housing also features a visible beam emitter that forms a visible light spot. This visible light spot indicates the position of the charging light spot, allowing for clear and intuitive location identification. Furthermore, if the position of the charging light spot deviates, an angle adjustment component adjusts the emission angles of both the visible beam emitter and the charging beam emitter, facilitating easier alignment between the transmitter and receiver.

[0006] In an optional embodiment, a channel is provided inside the main housing, through which the charging beam emitted by the charging beam emitter passes. A mounting part for mounting the visible beam emitter is provided inside the channel, and the mounting part is located at the center of the cross-section of the channel.

[0007] The main housing has a channel that allows the charging beam emitted by the charging beam emitter to pass through and illuminate the photovoltaic cell, resulting in a circular charging beam spot. A mounting part is also located within the channel, at the center of its cross-section. This mounting part allows the visible beam emitter to be installed at the center of the channel's cross-section, ensuring the visible beam spot is centered on the charging beam spot. The visible beam spot clearly indicates the center of the charging beam spot, making it easier to determine its position and improving alignment accuracy.

[0008] In one optional embodiment, the visible light beam emitting unit includes a plurality of emitting sub-units, the visible light spot includes a plurality of sub-spots, each of the emitting sub-units corresponds one-to-one with each of the sub-spots, and each of the sub-spots is located on the outer periphery of the charging light spot.

[0009] The visible beam emitting unit is composed of multiple emitting sub-units, and each emitting sub-unit forms a sub-spot, so that each emitting sub-unit corresponds one-to-one with each sub-spot. At the same time, each sub-spot is located on the outer periphery of the charging beam spot, and the outline of the charging beam spot can be clearly indicated by the sub-spots, making it easier to determine the position of the charging beam spot, thereby improving the alignment accuracy.

[0010] In one optional embodiment, a channel is provided inside the main housing, through which the charging beam emitted by the charging beam emitter passes. A plurality of mounting portions are provided around the channel on the main housing, and each of the emitting sub-parts is respectively mounted in the corresponding mounting portion.

[0011] Multiple emitting sub-units constitute a visible beam emitting unit, and each emitting sub-unit forms a sub-spot, so that each emitting sub-unit corresponds one-to-one with each sub-spot. At the same time, each sub-spot is located on the outer periphery of the charging spot, and the outline of the charging spot can be clearly indicated by the sub-spots, making it easier to determine the position of the charging spot, thereby improving the alignment accuracy.

[0012] In one alternative embodiment, the main housing includes a first housing and a second housing, the charging beam emitting part is disposed on the first housing, the visible beam emitting part is disposed on the second housing, and the second housing is detachably connected to the first housing.

[0013] The charging beam emitter is mounted on the first housing, and the visible beam emitter is mounted on the second housing. The second housing is detachably connected to the first housing. When alignment is required using the visible beam emitter, the first housing is connected to the second housing. After adjustment, the first housing is removed from the second housing to prevent the visible beam emitter from obstructing the charging beam.

[0014] In one alternative embodiment, the first housing has a first connecting portion, the second housing has a second connecting portion, and the first connecting portion and the second connecting portion are threadedly connected.

[0015] By having a first connecting part on the first housing and a second connecting part on the second housing, and by using a threaded connection between the first connecting part and the second connecting part, the first housing and the second housing can be disassembled and connected, making it more convenient to disassemble and connect the two.

[0016] In one optional embodiment, the angle adjustment assembly includes a fixed base, a rotating ball, and a connector. The fixed base is provided with a mounting recess for accommodating the rotating ball, and the rotating ball is rotatably fitted inside the mounting recess.

[0017] A mounting recess is provided on the fixed base, and a rotating ball is rotatably positioned within the mounting recess. One end of a connector is connected to the rotating ball, and the other end is connected to the light source emitting assembly. The connector is ball-connected to the fixed base via the rotating ball. When the illumination angle of the charging beam emitting section and the visible beam emitting section needs to be adjusted, the illumination angle can be adjusted by rotating the connector.

[0018] In one optional embodiment, the visible light beam emitted by the visible light beam emitting unit is a laser, and the charging light beam emitted by the charging light beam emitting unit is infrared light.

[0019] By using laser light as the visible beam, the beam can be more focused, preventing it from diverging over long distances and thus affecting the area of ​​the visible light spot.

[0021] A collimating lens is provided on the main housing, and the charging beam emitter is located at the focal point of the collimating lens, so that the charging beam emitted by the charging beam emitter is refracted by the collimating lens and then emitted, thereby making the divergence angle of the charging beam smaller.

[0022] In a second aspect, a door lock is provided, including the wireless charging device described in any of the preceding claims.

[0023] The first aspect of this invention provides the following technical advantages: By simultaneously mounting both the visible light beam emitter and the charging light beam emitter on the main housing and connecting the receiver to the power supply, the charging beam emitted by the charging beam emitter illuminates the photovoltaic cell during charging. The photovoltaic cell then converts the energy carried in the charging beam into electrical energy. Compared to existing technologies, the addition of a visible light beam emitter on the main housing allows for the formation of a visible light spot, which indicates the position of the charging light spot. This enables clear and intuitive identification of the charging light spot's location. Furthermore, if the position of the charging light spot deviates, the angle adjustment component can adjust the emission angles of both the visible light beam emitter and the charging light beam emitter, facilitating easier alignment between the transmitter and receiver.

[0040] Please refer to Figures 1 to 4 As shown, in a first aspect of this utility model embodiment, a wireless charging device is provided. The wireless charging device includes a transmitter 10 and a receiver 20. The receiver 20 includes a photovoltaic cell. The transmitter 10 includes a main housing 11, a visible light beam emitting part 12, a charging light beam emitting part 13, and an angle adjustment component 17. The visible light beam emitting part 12 and the charging light beam emitting part 13 are disposed on the main housing 11. The angle adjustment component 17 is used to adjust the emission angle of the visible light beam emitting part 12 and the charging light beam emitting part 13. The visible light beam emitting part 12 is used to form a visible light spot, and the charging light beam emitting part 13 is used to form a charging light spot. The visible light spot is used to indicate the position of the charging light spot.

[0041] Specifically, the main housing 11 refers to a shell-shaped component with a certain volume, and a certain amount of space can be provided inside the main housing 11 to accommodate other components. The visible beam emitting unit 12 refers to a device or component that can emit a visible beam of light, the color of which can be red, green, or yellow, etc. To ensure the concentration of the beam, the visible beam emitting unit 12 can be a laser emitter. A visible light spot refers to a spot of light with a certain area that can be seen by the human eye when a visible beam of light shines on an object.

[0042] The charging beam emitter 13 refers to a device or component capable of emitting a charging beam, which may be a near-infrared beam or the like. The charging spot refers to the spot of light formed by the charging beam illuminating the photovoltaic cell, which is invisible to the human eye. The angle adjustment component 17 refers to a mechanism or component capable of adjusting the angle between two objects.

[0043] The wireless charging device provided in this embodiment of the invention features a visible light beam emitter 12 and a charging light beam emitter 13 both mounted on the main housing 11, with the receiver 20 connected to the power-consuming device. During charging, the charging light beam emitted by the charging light beam emitter 13 illuminates a photovoltaic cell, which converts the energy carried in the charging light beam into electrical energy. Compared to existing technologies, the main housing 11 also includes a visible light beam emitter 12, which forms a visible light spot. This visible light spot indicates the position of the charging light spot, allowing for clear and intuitive identification. Furthermore, if the position of the charging light spot deviates, the angle adjustment component 17 adjusts the emission angles of the visible light beam emitter 12 and the charging light beam emitter 13, making alignment between the transmitter 10 and the receiver 20 easier.

[0044] In one embodiment, see Figure 2 and Figure 3The main housing 11 is provided with a channel 18, through which the charging beam emitted by the charging beam emitting unit 13 passes. The channel 18 is provided with a mounting part 14, which is used to mount and fix the visible beam emitting unit 12, and the mounting part 14 is located at the center of the cross-section of the channel 18.

[0045] Specifically, channel 18 refers to a receiving structure of a certain length. Both ends of channel 18 can be open structures. The charging beam emitting part 13 can be located at one end of channel 18, and the charging beam emitted by the charging beam emitting part 13 can be emitted from the other end after passing through channel 18. Mounting part 14 refers to a structure or component that can fix other objects. Mounting part 14 can be a clamping tube, clamping groove, or clamping hole, etc.

[0046] In this embodiment, a channel 18 is provided within the main housing 11, allowing the charging beam emitted by the charging beam emitter 13 to pass through the channel 18 and illuminate the photovoltaic cell, resulting in a circular charging beam spot shape under the influence of the channel 18. Simultaneously, a mounting portion 14 is provided within the channel 18, located at the center of the channel's cross-section. This allows the visible beam emitter 12 to be mounted at the center of the channel's cross-section, ensuring the visible beam spot is positioned at the center of the charging beam spot. The visible beam spot clearly indicates the center of the charging beam spot, making it easier to determine its location and improving alignment accuracy.

[0047] In an optional embodiment, please refer to Figure 3 The mounting part 14 includes an insertion tube part 141. Specifically, the insertion tube part 141 refers to a cylindrical component with a certain length. The insertion tube part 141 may have an opening at one end, or it may have openings at both ends. The visible beam emitting part 12 is inserted into the insertion tube part 141 through the opening at the end of the insertion tube part 141, making the installation of the visible beam emitting part 12 more convenient and secure.

[0048] It should be noted that a clearance opening is also provided on the side wall of the insert cylinder 141. The clearance opening is used to avoid the operating switch on the visible beam emitting unit 12, making the installation of the visible beam emitting unit 12 more convenient.

[0049] Based on the aforementioned feature insert sleeve 141, please refer to Figure 3 and Figure 4Multiple support members 16 are connected between the insert cylinder 141 and the inner wall of the channel 18. Specifically, the support member 16 refers to a component with a certain volume, and the support member 16 can be block-shaped, column-shaped, or plate-shaped, etc. By connecting the insert cylinder 141 to the inner wall of the channel 18 through multiple support members 16, the installation of the insert cylinder 141 in the channel 18 can be more secure, and also more stable and reliable.

[0050] Furthermore, the support member 16 can be plate-shaped, arranged radially along the mounting cylinder, and parallel to the axis of the channel 18. Specifically, plate-shaped support member 16 means that the support member is a component with a certain thickness. In this embodiment, by setting the support member 16 as plate-shaped, arranging it radially along the channel 18, and paralleling it to the axis of the channel 18, the support member 16 not only supports the insertion cylinder portion 141 but also reduces its area in the direction of the charging beam, avoiding excessive obstruction of the charging beam, increasing the overall area of ​​the charging spot, and improving the charging efficiency of the wireless charging device.

[0051] In one embodiment, see Figure 5 The visible beam emitting unit 12 includes multiple emitting sub-units 121, and the visible light spot includes multiple sub-spots. Each emitting sub-unit 121 corresponds one-to-one with each sub-spot, and each sub-spot is located on the outer periphery of the charging light spot. Specifically, the emitting sub-unit 121 refers to a component or assembly that can emit visible light, and the emitting sub-unit 121 can be a laser emitter. A sub-spot refers to a light spot area with a certain area.

[0052] In this embodiment, a visible light beam emitting unit 12 is composed of multiple emitting sub-units 121, and each emitting sub-unit 121 forms a sub-spot, so that each emitting sub-unit 121 corresponds one-to-one with each sub-spot. At the same time, each sub-spot is located on the outer periphery of the charging spot, so that the outline of the charging spot can be clearly indicated by the sub-spots, making it easier to determine the position of the charging spot, thereby improving the alignment accuracy.

[0053] In one embodiment, see Figure 5The main housing 11 has a channel 18, through which the charging beam emitted by the charging beam emitter 13 passes. Multiple mounting portions 14 are arranged around the channel 18 on the main housing 11, and each emitting sub-unit 121 is mounted in its corresponding mounting portion 14. Specifically, the channel 18 refers to a receiving structure of a certain length, and both ends of the channel 18 can be open. The charging beam emitter 13 can be located at one end of the channel 18, and the charging beam emitted by the charging beam emitter 13 can exit from the other end after passing through the channel 18. The mounting portion 14 refers to a structure or component that can fix other objects; the mounting portion 14 can be a clamping cylinder, clamping groove, or clamping hole, etc. In this embodiment, by providing multiple mounting portions 14 around the channel 18 on the main housing 11, mounting positions can be provided for multiple emitting sub-units 121, allowing the sub-spots formed by the emitting sub-units 121 to be located on the outer periphery of the charging beam spot. This allows the outline of the charging spot to be clearly indicated through the sub-spot, making it easier and faster to determine the position of the charging spot, thereby improving the accuracy of the alignment between the transmitter 10 and the receiver 20.

[0054] In one embodiment, see Figure 2 The main housing 11 includes a first housing 111 and a second housing 112. A charging beam emitter 13 is disposed on the first housing 111, and a visible beam emitter 12 is disposed on the second housing 112.

Specifically, both the first housing 111 and the second housing 112 refer to shell-shaped components with a certain volume, and the first housing 111 and the second housing 112 can be detachably connected by means of plugging, snapping, or threaded connection. In this embodiment, the charging beam emitter 13 is disposed on the first housing 111, and the visible beam emitter 12 is disposed on the second housing 112. The second housing 112 is detachably connected to the first housing 111. When alignment is required using the visible beam emitter 12, the first housing 111 is connected to the second housing 112. After adjustment, the first housing 111 is removed from the second housing 112 to prevent the visible beam emitter 12 from obstructing the charging beam.

[0055] In one embodiment, see Figure 2The first housing 111 has a first connecting portion 1111, and the second housing 112 has a second connecting portion 1121, with the first connecting portion 1111 and the second connecting portion 1121 being threadedly connected. Specifically, the first connecting portion 1111 refers to a component with a certain volume, which can be cylindrical or cylindrical, etc. The second connecting portion 1121 can also be a component with a certain volume, wherein when the first connecting portion 1111 is cylindrical, the second connecting portion 1121 can be cylindrical. In this embodiment, by having the first connecting portion 1111 on the first housing 111 and the second connecting portion 1121 on the second housing 112, and by the threaded connection between the first connecting portion 1111 and the second connecting portion 1121, the first housing 111 and the second housing 112 can be detachably connected, making disassembly and connection of the two more convenient.

[0056] In an optional embodiment, please refer to Figures 3 to 5 The second housing 112 is generally cylindrical, and the second connecting part 1121 can be one end of the second housing 112. The first connecting part 1111 is a columnar part on the first housing 111, which can fit the end of the second housing 112 onto the outside of the first connecting part 1111 on the first housing 111, and make the inner wall of the second housing 112 threadedly connected to the outer wall of the first connecting part 1111, making it easier to connect the first housing 111 and the second housing 112.

[0057] In one embodiment, see Figure 2 and Figure 6 The angle adjustment assembly 17 includes a fixed base 171, a rotating ball 172, and a connector 173. The fixed base 171 is provided with a mounting recess 174 for accommodating the rotating ball 172. The rotating ball 172 is rotatably locked inside the mounting recess 174. One end of the connector 173 is connected to the rotating ball 172, and the other end is connected to the main housing 11.

[0058] Specifically, the mounting base 171 refers to a component with a certain volume, which can be installed to a wall or other fixed location by means of plug-in, snap-fit, or fastener connection. The rotating ball 172 refers to a spherical structure with a certain diameter. The mounting recess 174 refers to a mounting part 14 with a certain accommodating space, the internal shape of which matches the rotating ball 172, allowing the rotating ball 172 to rotate within the mounting recess 174. The connector 173 refers to a component with a certain length, which can be rod-shaped, column-shaped, or plate-shaped. The connector 173 can be a separate structure from the rotating ball 172, connected by plug-in or threaded connection, or it can be an integral structure with the rotating ball 172. The other end of the connector 173 can be connected to the main housing 11 by plug-in, snap-fit, or threaded connection.

[0059] In this embodiment, a mounting recess 174 is provided on the fixed base 171, and a rotating ball 172 is rotatably disposed within the mounting recess 174. Simultaneously, one end of the connector 173 is connected to the rotating ball 172, and the other end is connected to the light source emitting assembly. The connector 173 is ball-connected to the fixed base 171 via the rotating ball 172. When the illumination angle of the charging beam emitting unit 13 and the visible beam emitting unit 12 needs to be adjusted, the illumination angle can be adjusted by rotating the connector 173.

[0060] In one embodiment, see Figure 2 The visible beam emitted by the visible beam emitting unit 12 is a laser, and the charging beam emitted by the charging beam emitting unit 13 is infrared light. Specifically, a laser refers to a beam with an extremely small divergence angle and high energy density. Infrared light refers to light waves with a wavelength range of approximately 0.76 micrometers to 1000 micrometers, with wavelengths between red light (the longest wavelength of visible light is approximately 0.76 micrometers) and microwaves (wavelength > 1 mm). The charging beam emitted by the charging beam emitting unit 13 can also be a laser or other beams with relatively high energy density. In this embodiment, by using a laser for the visible beam, the visible beam can be more concentrated, avoiding divergence after traveling a long distance, which would affect the area of ​​the visible light spot. Using infrared light for the charging beam allows the charging beam to carry more energy, thereby improving the efficiency of energy transfer.

[0061] In one embodiment, see Figure 2 The main housing 11 is also provided with a collimating lens 15, and the charging beam emitting part 13 is located at the focal point of the collimating lens 15. Specifically, the collimating lens 15 is an optical element used to convert diverging light into a parallel beam. In this embodiment, by providing a collimating lens 15 on the main housing 11 and placing the charging beam emitting part 13 at the focal point of the collimating lens 15, the charging beam emitted by the charging beam emitting part 13 is refracted by the collimating lens 15 before being emitted, thereby making the divergence angle of the charging beam smaller.

[0062] It should be noted that the collimating lens 15 can be part of the first housing 111. When the collimating lens 15 is present, the second housing 112 can be cylindrical, and the second housing 112 can be fitted onto the end of the collimating lens 15. The inner wall of the second housing 112 is threadedly connected to the outer wall of the collimating lens 15, making the installation of the second housing 112 more secure.

[0063] Secondly, a door lock is provided, comprising the wireless charging device of any of the above claims, and a lock body, wherein the lock body is electrically connected to the receiver 20. It is understood that the beneficial effects of the second aspect are described in the relevant description of the first aspect above, and will not be repeated here.
