Detailed Implementation

[0022] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application. Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0023] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0024] This application provides a portable power supply device that can provide power to a device to be charged via a wire, wirelessly, or a combination of both. The device to be charged can be an electronic device such as a mobile phone, tablet, or headset.

[0025] See Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of an embodiment of the second housing provided in this application in its extended state; Figure 2This is a schematic diagram of an embodiment of the second housing in its retracted state provided in this application. The power supply device 10 of this application includes a first housing 120, a power supply body, and a second housing 130. The power supply body is configured to output a power supply signal to provide power to the device to be charged. The first housing 120 forms a receiving cavity, and the power supply body is disposed within the receiving cavity, protecting the power supply body. The second housing 130 is disposed on one side of the first housing 120, and the second housing 130 is telescopically arranged relative to the first housing 120, that is, the second housing 130 can telescopically extend along the arrangement direction of the first housing 120 and the second housing 130. When the housing is in the extended state, the second housing 130 and the first housing 120 together form a storage cavity with an opening 131, which is used to accommodate items. When the second housing is in the retracted state, or in its retracted state, the second housing 130 is close to or adheres to the first housing 120, at which time the capacity of the storage cavity is very small or almost non-existent.

[0026] The orientation of the opening 131 of the storage cavity can be the same as the arrangement direction, or the orientation of the opening 131 can be perpendicular to the arrangement direction or the extension and retraction direction of the second housing 130, which is not limited here.

[0027] Unlike existing technologies, the power supply device 10 of this application adds a second housing 130 that is telescopically arranged relative to the first housing 120, so that the power supply device 10 of this application has a storage cavity for accommodating items when the second housing is in the extended state, which can enrich the functions of the power supply device 10, increase the application scenarios of the power supply device 10, and improve the user experience; in addition, in the stored state, the power supply device 10 can maintain or be close to the original small volume.

[0028] In one embodiment, in order to increase the capacity of the storage cavity while ensuring that the overall volume of the power supply device 10 occupies a small space, the first housing 120 includes a first sidewall 121 and a second sidewall 122 connected to each other, wherein the area of ​​the first sidewall 121 is larger than the area of ​​the second sidewall 122. The second housing 130 is disposed on one side of the first sidewall 121 and is telescopic relative to the first sidewall 121.

[0029] In one embodiment, the opening 131 of the storage cavity is oriented perpendicular to the arrangement direction of the first housing 120 and the second housing 130, or in other words, the opening 131 is oriented on the same side as the second sidewall 122. When the housing is in the extended state, the area of ​​the second sidewall 122 is small, making it easy to carry.

[0030] In one embodiment, the second housing 130 includes two first folded portions 132 and a support portion 133. The two first folded portions 132 are spaced apart along a first direction, one end of each first folded portion 132 is connected to the first housing 120, and the other end of each first folded portion 132 is retractable relative to the first housing 120 along the arrangement direction. The first direction, the arrangement direction, and the orientation of the opening 131 are perpendicular to each other. The support portion 133 is connected to the first housing 120 and the side of the first folded portions 132 away from the first housing 120. In this embodiment, when the second housing 130 is in the extended state, the two first folded portions 132 and the support portion 133, together with the side wall of the first housing 120, form a storage cavity with an opening 131, enabling the power supply device 10 to have a storage function. Furthermore, when the second housing 130 is in the retracted state, the first folded portions 132 fold to form a multi-layered structure, maintaining the small volume of the power supply device 10.

[0031] In one embodiment, the first folding portion 132 may be composed of multiple folding units (not shown), and two adjacent folding units adopt a foldable structure to achieve folding. By extending different numbers of folding units, the storage cavity capacity can be adjusted.

[0032] In one embodiment, the second housing 130 further includes a connecting portion 134, which is connected to the first housing 120, the two first folding portions 132, and the support portion 133. The length of the connecting portion 134 in the arrangement direction is adjustable. The connecting portion 134 is disposed opposite to the opening 131. Understandably, in this embodiment, the connecting portion 134 can serve as the bottom of the receiving cavity, disposed opposite to the opening 131. In other embodiments, the two first folding portions 132 are replaced by two connecting portions 134, and the connecting portions 134 are replaced by first folding portions 132. In this case, the first folding portions 132 can serve as the bottom of the receiving cavity, disposed opposite to the opening 131.

[0033] The connecting portion 134 can be a flexible connecting portion 134, such as a braided connecting portion 134 or a silicone connecting portion 134, etc., without limitation. The flexible connecting portion 134 can change its length relative to the first housing in the arrangement direction by bending, compression, etc. Alternatively, the connecting portion 134 includes a second folded portion, wherein the second folded portion has the same function as the first folded portion 132, and the structure of the first folded portion 132 can be referred to for details, which will not be repeated here.

[0034] In one embodiment, the first folding portion 132, the connecting portion 134, and the supporting portion 133 are integrally formed.

[0035] In one embodiment, the second housing 130 is slidably connected to the first housing 120 along the arrangement direction, such that the second housing 130 has an extended state and a retracted state relative to the first housing 120. Understandably, in the extended state, the second housing 130 is located away from the first housing 120 along the arrangement direction, and together with the first housing 120, forms a storage cavity with an opening 131; in the retracted state, the second housing 130 is located close to the first housing 120. For ease of understanding, the second housing 130 can be considered as a drawer in daily life; the extended state can be understood as the drawer being pulled out; and the retracted state can be understood as the drawer being closed.

[0036] In this embodiment, the power supply device 10 achieves a retractable storage space by providing a second housing 130 that is slidably connected to the first housing 120. This method is simple and easy to implement.

[0037] In one embodiment, the second housing 130 can be slidably connected to the first housing 120 in a first-stage sliding connection and a second-stage sliding connection. The capacity of the storage cavity in the first stage is smaller than that in the second stage, allowing the user to adjust the capacity of the storage cavity as needed, thus improving the user experience.

[0038] In one embodiment, the power supply device 10 further includes a cover 140. The cover 140 is connected to the first housing 120, or to the second housing 130, or to both the first housing 120 and the second housing 130; this is not limited. The cover 140 is at least configured with an opening 131. That is, the power supply device 10 of this embodiment achieves the opening and closing of the opening 131 by providing the cover 140. When the opening 131 is closed, it provides the user with invisible storage space, ensuring the privacy of the user's belongings and improving the user experience.

[0039] In one embodiment, one end of the cover 140 is connected to the first housing 120, and the other end of the cover 140 extends to the second housing 130. The cover 140 covers the same side of the first housing 120 and the second housing 130, with the opening 131 located on one side. That is, in both the extended and retracted states, the other end of the cover 140 in this embodiment can cover the first housing 120, the second housing 130, and the opening 131, ensuring that the opening 131 can be opened and closed while maintaining the aesthetic appeal of the power supply device 10, thereby improving the user experience.

[0040] In one embodiment, the cover 140 includes a flexible cover 140, and the cover 140 may also be a foldable cover 140, which is not limited here.

[0041] For example, the cover 140 can be bent to present a certain arc. One side of the cover 140 is fixedly connected to the first housing 120, and the other side of the cover 140 can rotate 180° horizontally to cover the first housing 120 and the opening 131 of the storage cavity.

[0042] In one embodiment, the power supply device 10 further includes a first connector 160 and a second connector 170. The first connector 160 is located at the end of the cover 140 away from the first housing 120, and the second connector 170 is located on the side of the second housing 130 opposite to the first housing 120. The first connector 160 and the second connector 170 are detachably connected. It can be understood that the power supply device 10 of this embodiment, by providing the detachably connected first connector 160 and second connector 170 on the cover 140 and the second housing 130, allows the cover 140 to better close the opening 131.

[0043] The first connector 160 and the second connector 170 can be detachably connected by magnetic attraction, snap-fit, or plug-in, without limitation. For example, the first connector 160 or the second connector 170 can be a permanent magnet, and correspondingly, the second connector 170 or the first connector 160 can be a permanent magnet that can attract the permanent magnet or a magnetic metal part; or the first connector 160 or the second connector 170 can be a female buckle, and correspondingly, the second connector 170 or the first connector 160 can be a female buckle; or the first connector 160 or the second connector 170 can be a magnetic female buckle, and correspondingly, the second connector 170 or the first connector 160 can be a magnetic female buckle.

[0044] In one embodiment, to improve the user experience, the power supply device 10 also includes a handle 150, which allows the user to carry the power supply device 10, thus providing portability. The handle 150 is connected to the first housing 120, and the connection point between the handle 150 and the first housing 120 is positioned close to the opening 131. This ensures that when the power supply device 10 is lifted, the orientation of the opening 131 remains the same as the extension direction of the handle 150, preventing items from falling out of the storage cavity due to the opening 131 facing in other directions, thereby improving the user experience.

[0045] In one embodiment, to improve the user experience, the handle 150 includes an adjustable length handle 150, which the user can freely adjust to a suitable length according to their needs. For example, adjusting the handle 150 to a length suitable for diagonal carrying allows the user to free their hands, and the power supply device 10 is worn on the user's body, reducing the chance of the power supply device 10 being dropped. Alternatively, adjusting it to a length convenient for hand carrying allows the power supply device 10 to function as a handbag.

[0046] The handle 150 can be a leather handle 150, a woven handle 150, a metal handle 150, etc., and there are no restrictions here.

[0047] In one embodiment, see Figure 3 , Figure 3 This is a schematic diagram of an embodiment of the power supply body provided in this application. The power supply body includes a power supply control circuit and a battery 112. The battery 112 is configured to output a DC power supply signal. In this embodiment, the power supply circuit provides a DC power supply signal to the entire system of the power supply device 10 by setting the battery 112, enabling the power supply device 10 to achieve a mobile function and making it convenient for users to carry.

[0048] In one embodiment, the power supply unit further includes an infrared circuit 114, a signal processing circuit 1192, and a display circuit 117 connected to the power supply control circuit 111. The display circuit 117 is connected to the power supply control circuit 111 and configured to receive the output signal of the power supply control circuit 111 and display a prompt signal corresponding to the output signal. The infrared circuit 114 is connected to the power supply control circuit 111 and is used for transmitting and receiving infrared signals. Specifically, the infrared circuit includes an infrared emitting tube and multiple infrared receiving sensors 1142. The infrared emitting tube is configured to emit a first infrared light of a preset frequency, and the infrared receiving sensors 1142 are configured to receive a second infrared light. The signal processing circuit 1192 is connected to both the infrared receiving sensors 1142 and the power supply control circuit 111. The signal processing circuit 1192 processes the infrared signals received by the infrared receiving sensors 1142 and outputs an electrical signal related to the distance and coordinates of the object. The power supply control circuit 111 determines the distance and coordinate information of the object relative to the power supply device 10 based on the output of the signal processing circuit 1192. The display circuit 117 is connected to the power supply control circuit 111 and is configured to receive the output signal of the power supply control circuit 111 and display a prompt signal corresponding to the output signal.

[0049] Specifically, the signal processing circuit 1192 processes the second infrared light from the infrared receiving sensor 1142 and outputs a DC voltage signal of the second infrared light at a preset frequency. The power supply control circuit 111 determines the distance information of the object reflecting the second infrared light at the preset frequency relative to the power supply device based on the first infrared light and the second infrared light at the preset frequency, and determines the coordinate information of the target object relative to the power supply device based on the position information of the infrared receiving sensor 1142 and its corresponding DC voltage signal. The coordinate information and distance information are then output to the display circuit 117.

[0050] The smoothness of an object's reflective surface or its absorption performance of infrared light varies, resulting in different signal intensities of the reflected infrared light. This embodiment utilizes these characteristics to determine whether an object reflecting a second infrared light of a preset frequency is a target object based on the signal intensity. Specifically, the infrared circuit emits a first infrared light of a preset frequency and receives a second infrared light. Since the second infrared light includes infrared light of other frequencies as well as infrared light of the preset frequency, the second infrared light of the preset frequency is the infrared light reflected back by the object when irradiated by the first infrared light of the preset frequency. To obtain the second infrared light of the preset frequency, the signal processing circuit 1192 performs signal processing on the second infrared light, filtering out second infrared light of other frequencies, and outputs a DC voltage signal of the second infrared light of the preset frequency. The DC voltage signal is used to characterize the signal intensity of the second infrared light of the preset frequency. The power supply control circuit 111 determines the distance information of the object reflecting the second infrared light of the preset frequency relative to the power supply device based on the first infrared light of the preset frequency and the second infrared light of the preset frequency, and determines the coordinate information of the target object relative to the power supply device based on the position information of the infrared receiving sensor 1142 and its corresponding DC voltage signal, and outputs the coordinate information and distance information to the display circuit 117. The display circuit 117 outputs the coordinate position and distance of the target object relative to the power supply equipment based on the coordinate information and distance information. At the same time, the display circuit 117 outputs the signal intensity of the second infrared light of the preset frequency reflected by the object based on the DC voltage signal.

[0051] Specifically, the power supply control circuit 111 can calculate the coordinates and distance information of the target object based on the position information of the infrared receiving sensor 1142, such as coordinates, signal strength, and round-trip time of the first and second infrared lights at preset frequencies, using algorithms such as triangulation and time-of-flight (ToF).

[0052] The target object in this embodiment can be a camera. That is, the power supply device in this embodiment can be used for the automatic detection of hidden cameras and to display the location of the cameras, which can enrich the application scenarios of the power supply device.

[0053] For example, in a specific application, if a pinhole camera is present in the reflection area of ​​the first infrared light, the pinhole camera will undergo specular reflection when it encounters the first infrared light of a preset frequency. Compared to diffuse reflection from walls or other objects around the camera, the signal strength of the second infrared light of the preset frequency reflected by the pinhole camera is greater. The power supply control circuit 111 determines the presence of a target object (pinhole camera) in the reflection area based on the signal strength. The power supply control circuit 111 calculates the position and distance information of the target object based on the position information of the infrared receiver corresponding to the signal strength and the round-trip time of the first and second infrared lights of the preset frequencies. Finally, the display circuit 117 displays prompts corresponding to the position, distance, and signal strength information, which can help the user locate the pinhole camera. For example, see [reference needed]. Figure 5 , Figure 5 This is a schematic diagram of an embodiment of the display circuit 117 provided in this application that displays prompt information corresponding to position information, distance information, and signal strength. The points on the coordinates represent the positions of the reflected objects in the coordinate axes. Different colors of the points can correspond to different signal strengths. When the color of the points changes from dark to light, representing the signal strength from strong to weak, the darker colored points can be regarded as pinhole cameras. This method can help users quickly check whether there are hidden cameras in their space.

[0054] In one embodiment, the signal processing circuit 1192 includes sub-signal processing circuits 1192 corresponding to the number of infrared receiving sensors 1142, with each sub-signal processing circuit 1192 corresponding to one of the infrared receiving sensors 1142. Each sub-signal processing circuit 1192 includes an amplifier circuit 1192a, a filter circuit 1192b, a synchronous demodulation circuit 1192c, and a peak detection circuit 1192d. The amplifier circuit 1192a is connected to the infrared receiving sensors 1142 and is configured to convert the second infrared light into an analog voltage signal. The filter circuit 1192b is connected to the amplifier circuit 1192a and is configured to output an analog voltage signal of a preset frequency. The synchronous demodulation circuit 1192c is connected to the filter circuit 1192b and is configured to output the DC envelope signal of the analog voltage signal. The peak detection circuit 1192d is connected to the synchronous demodulation circuit 1192c and the power supply control circuit 111 and is configured to convert the DC envelope signal into a DC voltage signal.

[0055] Understandably, the signal processing circuit 1192 of this embodiment includes the same number of sub-signal processing circuits 1192 as the number of infrared receiving sensors 1142, such that each infrared receiving sensor 1142 is connected to one sub-signal processing circuit 1192. Specifically, the amplification circuit 1192a converts the photocurrent signal of the infrared receiving sensor 1142 into an analog electrical signal, the filtering circuit 1192b filters the analog electrical signal, and outputs only an analog voltage signal of a preset frequency; the synchronous demodulation circuit 1192c extracts the DC envelope signal of the analog voltage signal of the preset frequency; and the peak detection circuit 1192d converts the DC envelope signal into a stable DC voltage signal. The signal processing circuit 1192 of this embodiment can process infrared light received by multiple infrared receiving sensors 1142 simultaneously, which can accelerate the detection speed of target objects in the power supply equipment; in addition, the sub-signal processing circuit 1192 has a simple structure and is easy to implement.

[0056] In one embodiment, in order to improve the detection accuracy of the target object's position, the infrared circuit includes six infrared receiving sensors 1142, which are arranged in a 2*3 rectangle.

[0057] In one embodiment, the power supply body further includes a first switch button 116 connected to the power supply control circuit 111 and the infrared circuit. The first switch button 116 is disposed in the first housing 120 and is configured to turn the infrared circuit 114 on or off. By providing the first switch button 116, the power supply device 10 of this embodiment can turn the infrared circuit 114 on or off by operating the first switch button 116, thereby reducing the power consumption of the infrared circuit 114.

[0058] In one embodiment, the battery 112 includes a lithium battery 112, which has functions such as stability and light weight, and can enhance the power supply reliability of the power supply device 10.

[0059] In one embodiment, to enhance the safety and reliability of the power supply device 10, the power supply circuit further includes a protection circuit 113, which is connected to both the power supply control circuit 111 and the battery 112. The protection circuit 113 monitors safety parameters of the battery 112, such as overcharging, over-discharging, overcurrent, and short circuit, protecting the battery 112 and the entire power supply device 10 circuit safety. The protection circuit 113 can be a battery management chip, or it can be a circuit composed of circuits with functions for overcharging, over-discharging, overcurrent, and short circuit of the battery 112; there are no limitations on this.

[0060] In one embodiment, the power supply device 10 further includes a power detection circuit 119 configured to detect the power of the battery 112.

[0061] In one embodiment, the prompt information can be of the type of sound, light, text, graphics, etc., and there can be one or more types of prompt information, which is not limited here.
