Description

Technical Field

[0001] This application relates to the technical field of mobile power supplies, and in particular to a charging device and an electronic device. Background Technology

[0002] With the improvement of living standards, electronic devices have been widely used. When using electronic devices, it is often necessary to use portable charging devices such as power banks to charge them. However, in the current technology, portable charging devices such as power banks mostly require users to prepare their own cables, and even those power banks that come with their own cables are often limited by the short length of the cables. Utility Model Content

[0003] This application provides a charging device to solve the problem of excessively short charging cables in existing technologies.

[0004] To solve the above-mentioned technical problems, this application provides a charging device, including: a housing, in which a first accommodating space is formed, and an opening communicating with the first accommodating space is provided on one end face of the housing in the length or width direction; and a wire, which is stacked in the first accommodating space to extend or retract into the first accommodating space through the opening.

[0005] The length of the first accommodating space is set along the first direction, and the width of the first accommodating space is set along the second direction. One of the first direction and the second direction is the length direction of the shell, and the other of the first direction and the second direction is the width direction of the shell.

[0006] The wire includes multiple extensions and multiple bends, which are arranged alternately. Each extension is arranged along a first direction when the wire is stored in the first receiving space, and the bends are used to connect adjacent extensions. The multiple extensions are arranged along a second direction when the wire is stored in the first receiving space.

[0007] The bending part is equipped with a memory element, or the bending part is a memory element.

[0008] The extension has a magnetic attraction part on its end face.

[0009] The wire has a flat structure.

[0010] The housing also forms a second accommodating space, and the charging device also includes a charging and discharging component, which is disposed in the second accommodating space. The second accommodating space is adjacent to the first accommodating space. One end of the wire is connected to the charging and discharging component, and the other end is provided with a charging connector.

[0011] The first accommodating space includes a first part and a second part that are connected. The first part is located close to the second accommodating space, and the second part is located away from the second accommodating space. The second part is connected to an opening, and the width of the second part is greater than the width of the first part. When the cable is stored in the first accommodating space, the charging connector is located in the second part. The cable is located at the end of the second part away from the first part when it is connected to the charging / discharging connection.

[0012] The housing has a locking part at the opening, the width of the part where the cable connects to the charging connector is a1, the width of the opening where the locking part is provided is a2, and the width of the opening where the locking part is not provided is a3, wherein a2 < a1 ≤ a3.

[0013] The part of the cable that connects to the charging connector has a corresponding protrusion. The width of the cable at the protrusion is b1, the width of the cable at other locations is b2, and the width of the opening is b3, wherein b2≤b3<b1.

[0014] The housing is equipped with a pressing part and a telescopic part at the opening. The telescopic part is extended and retracted by the pressing part, and the wire is fixed by the telescopic part.

[0015] To address the aforementioned problems, this application also provides an electronic device including a charging device according to any of the above-mentioned methods.

[0016] The beneficial effects of this application are as follows: Unlike existing technologies, this application effectively avoids the problem of easy loss of the cable by forming a first accommodating space on the housing and placing the cable within the first accommodating space. Furthermore, the cable is neatly stored inside the housing by folding, preventing tangling. An opening communicating with the first accommodating space is provided on the housing, allowing the cable to be flexibly stretched, ensuring the convenience and flexibility of the charging device.

[0029] Please see Figure 1 , Figure 1 This is a schematic diagram of an embodiment of the charging device provided in this application.

[0030] This application provides a charging device. For example... Figure 1As shown, the charging device of this embodiment includes a housing 10 and a wire 20. A first accommodating space 11 is formed in the housing 10. An opening 12 communicating with the first accommodating space 11 is provided on one end face of the housing 10 in the length or width direction. The wire 20 is stacked in the first accommodating space 11, extending or retracting through the opening 12 into the first accommodating space 11. The wire 20 is accommodated in the first accommodating space 11 of the housing 10, meaning the wire 20 can be integrally formed with the housing 10, thus facilitating the carrying of the charging device. The charging device can be a power bank or other portable power source; this application does not specifically limit its application.

[0031] In an optional embodiment, a housing 10 with a first accommodating space 11 is provided, and the charging cable 20 is disposed in the first accommodating space 11, thereby folding and storing the cable 20. Specifically, an opening 12 communicating with the first accommodating space 11 is formed on the housing 10. When storing the cable 20, it can be stored into the first accommodating space 11 through the opening 12. That is, by providing the first accommodating space 11 on the housing 10, the cable 20 is folded to be stored into the first accommodating space 11 when storing it, thereby effectively avoiding the cable 20 from easily tangling during storage. Furthermore, by providing the first accommodating space 11 to store the cable 20, the cable 20 can be neatly stored, and the cable 20 can be flexibly stretched when charging.

[0032] In some embodiments, the wire 20 can be integrally formed with other components within the housing 10, meaning the wire 20 is connected to the housing 10 and is folded within the first accommodating space 11. When storing the wire 20, its sidewalls abut against the inner sidewalls of the first accommodating space 11, allowing the wire 20 to be neatly stored within the space, effectively preventing tangling and loss. Furthermore, when using the charging device, the wire 20 can be pulled out of the first accommodating space 11 through the upper opening 12 of the housing 10, ensuring the convenience and flexibility of the charging device.

[0033] In the above embodiment, by forming a first accommodating space 11 on the housing 10 and placing the wire 20 in the first accommodating space 11, the problem of the wire 20 being easily lost is effectively avoided. Furthermore, by using a folding method to store the wire 20, it can be neatly stored inside the housing 10, preventing the wire 20 from easily tangling. An opening 12 communicating with the first accommodating space 11 is provided on the housing 10, through which the wire 20 can be flexibly stretched, ensuring the convenience and flexibility of the charging device.

[0034] In an optional embodiment, the length direction of the first accommodating space 11 is arranged along a first direction, and the width direction of the first accommodating space 11 is arranged along a second direction. One of the first direction and the second direction is the length direction of the housing 10, and the other of the first direction and the second direction is the width direction of the housing 10. That is, the first direction can be the length direction of the housing 10, and the second direction can be the width direction of the housing 10. In other words, the first accommodating space 11 formed on the housing 10 is disposed on the side wall of the housing 10 along the length direction and extends into the housing 10 along the width direction. At this time, the wire 20 is accommodated in the first accommodating space 11 on the side wall of the housing 10 along the length direction.

[0035] In other embodiments, the first direction may be the width direction of the housing 10, and the second direction may be the length direction of the housing 10. That is, the first accommodating space 11 formed on the housing 10 is disposed on the side wall in the width direction of the housing 10 and extends towards the interior of the housing 10 along the length direction of the housing 10. At this time, the wire 20 is accommodated in the first accommodating space 11 on the side wall in the width direction of the housing 10.

[0036] The first accommodating space 11 is disposed on the side wall of the housing 10 in the length or width direction, or it may be partially disposed in the length direction and partially disposed in the width direction of the housing 10. The specific configuration can be determined according to the requirements, and this application does not make any specific limitations.

[0037] In an optional embodiment, such as Figure 2 As shown, the wire 20 includes multiple extensions 21 and multiple bends 22, which are alternately arranged. Each extension 21 is arranged along a first direction when the wire 20 is stored in the first receiving space 11, and the bends 22 are used to connect adjacent extensions 21. The multiple extensions 21 are arranged along a second direction when the wire 20 is stored in the first receiving space 11. Specifically, the wire 20 is provided with multiple extensions 21 and multiple bends 22, that is, the extensions 21 and bends 22 are connected sequentially to form the wire 20. When storing the wire 20, it can be folded along the bends 22 to neatly store the wire 20. When the wire 20 is stored in the first receiving space 11, the multiple extensions 21 abut against each other, thereby effectively reducing the volume occupied by the wire 20 in the first receiving space 11.

[0038] In this embodiment, when the wire 20 is stored in the first accommodating space 11, multiple extensions 21 are arranged along a first direction and abut against each other. These abutting extensions 21 can be arranged along a second direction to complete the storage of the wire 20. Specifically, when the first accommodating space 11 is located on the side wall along the length of the housing 10, after storing the wire 20, multiple extensions 21 are arranged within the first accommodating space 11 along the length of the housing 10 and along the width of the housing 10. By providing multiple extensions 21 and multiple bends 22, the neatness of the stored wire 20 can be ensured, and storage is more convenient.

[0039] In some embodiments, combined with Figure 8 and Figure 9 As shown, when the charging device is needed, the cable 20 can be pulled, causing it to stretch along the bend 22 and extend out of the first accommodating space 11. Specifically, when using the charging device, the length of the cable 20 can be controlled according to the pulling force, that is, by controlling the included angle of the bend 22, or by controlling the included angle between the extensions 21 at both ends of the bend 22, thereby controlling the length of the cable 20. In other words, when using the charging device, the length of the cable 20 can be controlled according to the pulling force.

[0040] In some embodiments, a memory element (not shown) is provided on the bending portion 22, or the bending portion 22 is a memory element. Specifically, the memory element can be sleeved on the outer wall of the wire 20, or multiple bending portions 22 of the wire 20 are all made of a material with memory and reset properties, that is, the bending portion 22 is a memory element. Obviously, due to the presence of the memory element, it has good recovery characteristics. When storing the wire 20, the wire 20 can be neatly stored into the first accommodating space 11 under the action of the memory element. That is, when storing the wire 20, the memory element can automatically fold, thereby completing the storage of the wire 20. Moreover, the width of the first accommodating space 11 needs to be greater than the width of the wire 20, so as to avoid the situation where the wire 20 gets stuck when storing it. In this embodiment, the memory element can specifically be a memory metal element, that is, the memory element is a memory metal. In other embodiments, the memory element may also be made of other memory materials, such as memory foam, and this application does not specifically limit it.

[0041] In this embodiment, the wire 20 may include conductive lines and an insulating layer. The insulating layer includes conductive lines, and the memory element disposed on the bend 22 can be connected to the conductive lines; that is, both the memory element and the conductive lines are wrapped by the insulating layer. In other embodiments, the memory element may also be disposed within the insulating layer, meaning the memory element does not contact the conductive lines. Alternatively, the memory element may be disposed on the outer wall of the insulating layer, meaning the memory element is sleeved on the outer wall of the wire 20.

[0042] In some embodiments, the extension portion 21 is provided with a magnetic attraction portion (not shown). The wire 20 is configured as a flat structure, meaning the magnetic attraction portion is located on both end faces of the flat wire 20. When storing the wire 20, the magnetic attraction portions between the multiple extension portions 21 can automatically fold the wire 20 under magnetic attraction, thus neatly storing it into the first accommodating space 11. The wire 20 is configured as a flat structure, meaning the cross-sectional shape of the wire 20 can be rectangular, trapezoidal, or other shapes, preferably rectangular. This prevents misalignment or tangling of the wire 20 during folding.

[0043] The cable 20 may be equipped with both a memory element and a magnetic attraction part. When storing the cable 20, the memory element and the magnetic attraction part work together to automatically fold the cable 20, facilitating storage and preventing tangling. In other embodiments, the memory element or the magnetic attraction part may be used; the specific configuration can be determined according to requirements and is not limited herein.

[0044] In some embodiments, combined with Figure 3 As shown, the housing 10 also forms a second accommodating space 13. The charging device further includes a charging and discharging assembly 30, which is disposed within the second accommodating space 13. The second accommodating space 13 is adjacent to the first accommodating space 11. One end of the wire 20 is connected to the charging and discharging assembly 30, and the other end is provided with a charging connector 23. The charging and discharging assembly 30 may include a battery 31, a charging and discharging circuit board 32, etc., meaning that the battery 31 and the charging and discharging circuit board 32 are both disposed within the second accommodating space 13. One end of the wire 20 is connected to the charging and discharging assembly 30. Specifically, the wire 20 may be connected to the charging and discharging circuit board 32, and various types of charging connectors 23 may be provided to adapt to different mobile devices, such as different models of mobile phones, watches, etc. This application does not make specific limitations here.

[0045] In this embodiment, the second accommodating space 13 is arranged adjacent to the first accommodating space 11. One end of the wire 20 is connected to the charging / discharging assembly 30, and the other end is connected to the charging connector 23. That is, an inner wall (not shown) can be formed inside the housing 10, which divides the internal space of the housing 10 into the first accommodating space 11 and the second accommodating space 13 to respectively accommodate the wire 20 and the charging / discharging assembly 30. Specifically, a first interface (not shown) located in the first accommodating space 11 and a second interface (not shown) located in the second accommodating space 13 can be respectively provided on both sides of the inner wall. The first interface is used to connect to the wire 20, and the second interface is used to connect to the charging / discharging assembly 30. This realizes the connection between the charging / discharging assembly 30 and the wire 20. Alternatively, a through hole (not shown) can be opened on the inner wall, through which the wire 20 can directly pass to establish a connection with the charging / discharging assembly 30, that is, the wire 20 is directly connected to the charging / discharging assembly 30.

[0046] In other embodiments, the first accommodating space 11 and the second accommodating space 13 can be connected, that is, there is no partition between the first accommodating space 11 and the second accommodating space 13, or there is no inner wall between the first accommodating space 11 and the second accommodating space 13. In this case, the wire 20 is directly connected to the charging and discharging assembly 30. The connection relationship between the charging and discharging assembly 30 and the wire 20 is not limited to the three types mentioned above, and this application does not make specific limitations here.

[0047] In an optional embodiment, such as Figure 3 As shown, a charging port 33 communicating with the charging and discharging assembly 30 can be provided on the housing 10. This charging port 33 is used to charge the charging and discharging assembly 30. Multiple charging ports 33 can be provided, and the charging ports 33 can include various types, such as USB (Universal Serial Bus)-A interfaces, USB-C interfaces, etc., which are not specifically limited here. Specifically, taking the first accommodating space 11 being located on the side wall along the length direction of the housing 10 as an example, a hole communicating with the second accommodating space 13 can be formed on the side wall along the width direction of the housing 10, and the charging port 33 can be disposed within this hole, so that when it is necessary to charge the charging device, it can be charged through the charging port 33.

[0048] In an optional embodiment, the first accommodating space 11 includes a first portion 111 and a second portion 112 that are connected. The first portion 111 is disposed close to the second accommodating space 13, and the second portion 112 is disposed away from the second accommodating space 13. The second portion 112 is connected to the opening 12, and the width of the second portion 112 is greater than the width of the first portion 111. When the wire 20 is stored in the first accommodating space 11, the charging connector 23 is disposed in the second portion 112. That is, the width of the first portion 111 along the thickness direction of the housing 10 is smaller than the width of the second portion 112, and the end of the wire 20 is provided with the charging connector 23. In other words, the first portion 111 is used to accommodate the folded wire 20, and the second portion 112 is used to accommodate the charging connector 23. It is understandable that a charging connector 23 is provided at one end of the cable 20. The width of the charging connector 23 is greater than the width of the cable 20. In order to facilitate the accommodation of the cable 20 and the charging connector 23, the width of the second part 112 used to accommodate the charging connector 23 needs to be greater than the width of the first part 111 used to accommodate the cable 20.

[0049] In this embodiment, taking the first accommodating space 11 disposed on the side wall along the length of the housing 10 as an example, the first portion 111 of the first accommodating space 11 is disposed at one end along the length of the housing 10, and the second portion 112 is disposed at the other end along the length of the housing 10. The first portion 111 of the first accommodating space 11 is disposed close to the second accommodating space 13, and the second portion 112 is disposed away from the second accommodating space 13. That is, the depth of the first portion 111 along the second direction is greater than the depth of the second portion 112, which in turn is greater than the depth of the second portion 112 along the width direction of the housing 10. This facilitates the placement of the cable 20 within the first portion 111, and ensures that the cable 20 and the charging connector 23 are flush at the opening 12 of the housing 10 after placement, thereby effectively improving the space utilization rate of the first accommodating space 11.

[0050] In an optional embodiment, such as Figure 3 As shown, the second portion 112 of the first accommodating space 11 can be used only to accommodate the charging connector 23. That is, after the second portion 112 accommodates the charging connector 23, the end face of the charging connector 23 can be flush with or slightly lower than the plane where the opening 12 of the housing 10 is located. After the first portion 111 accommodates the wire 20, the end face of the wire 20 is flush with or slightly lower than the plane where the opening 12 of the housing 10 is located. Therefore, the depth of the first portion 111 along the second direction is greater than the depth of the second portion 112, which can effectively improve the space utilization of the first accommodating space 11, thereby effectively improving the layout capability when installing internal components of the housing 10.

[0051] In an optional embodiment, such as Figure 4As shown, after the cable 20 and charging connector 23 are stored in the first accommodating space 11, a locking part 40 can be provided at the opening 12 of the housing 10 to secure them. This locking part 40 secures the cable 20 after it is stored in the first accommodating space 11. Figure 5 As shown, Figure 5 for Figure 4 The enlarged structural diagram at point A shows that the width of the portion of the cable 20 connecting to the charging connector 23 is a1, the width of the opening 12 with the locking part 40 is a2, and the width of the opening 12 without the locking part 40 is a3, where a2 < a1 ≤ a3. In other words, the width of the portion of the cable 20 connecting to the charging connector 23 is a1, which is the width of the cable 20 itself. The width of the opening 12 with the locking part 40 is a2. To secure the cable 20 with the locking part 40, the width a2 of the opening 12 needs to be smaller than the width a1 of the cable 20. Because the width a2 of the opening 12 with the locking part 40 is smaller than the width a1 of the cable 20, after the cable 20 is placed into the first receiving space 11, the cable 20 will abut against the locking part 40, thus preventing the cable 20 from detaching from the first receiving space 11. Understandably, the width of the opening 12 where the retaining part 40 is located cannot be too small to avoid inconvenience when storing the cable 20. Furthermore, the width of the cable 20 is a1, and the width of the opening 12 without the retaining part 40 is a3. In order to store the cable 20 into the first receiving space 11, the width a1 of the charging cable needs to be less than or equal to the width a3 of the opening 12 without the retaining part 40. That is, the cable 20 can be stored into the first receiving space 11. Note that the dimensions described above do not include the dimensions of the charging connector 23 or the dimensions of the first receiving space 11 that accommodates the charging connector 23.

[0052] In this embodiment, two locking portions 40 can be provided on opposite sides of the edge of the opening 12, that is, two locking portions 40 are symmetrically provided at the edge of the opening 12 to lock the wire 20. Furthermore, two sets of locking portions 40 can be arranged along the first direction. For example, when the first accommodating space 11 is located at the edge of the housing 10 along its length, two sets of locking portions 40 are arranged along the length of the housing 10. One set corresponds to the first portion 111 of the first accommodating space 11, and the other set corresponds to the second portion 112 of the first accommodating space 11. Moreover, to accommodate the wire 20 at the edge, the locking portion 40 corresponding to the first portion 111 can be positioned close to the second portion 112.

[0053] In other embodiments, the locking part 40 may be disposed on one side of the edge of the opening 12. When two sets of locking parts 40 are disposed along the first direction, the two sets of locking parts 40 are staggered. For example, the locking part 40 disposed on the first part 111 of the first accommodating space 11 may be located on one side of the edge of the opening 12, and the locking part 40 disposed on the second part 112 of the first accommodating space 11 may be located on the other side of the edge of the opening 12, thereby locking and fixing the wire 20 by the two staggered locking parts 40. The arrangement of the locking part 40 can be set according to the requirements, and this application does not make specific limitations here.

[0054] In some embodiments, such as Figure 6 As shown, the portion of the cable 20 that connects to the charging connector 23 has a corresponding protrusion 50. When the cable 20 is inserted into the first receiving space 11, the protrusion 50 can engage with the inner wall of the first receiving space 11, meaning the protrusion 50 on the cable 20 engages with the inner wall of the housing 10 forming the first receiving space 11. After the cable 20 is inserted into the first receiving space 11, the engagement of the protrusion 50 with the inner wall of the first receiving space 11 secures and fixes the cable 20, preventing it from popping out of the first receiving space 11. Combined with... Figure 7 As shown, Figure 7 for Figure 6 The enlarged structural diagram at point B shows that, specifically, the width of the wire 20 with the protrusion 50 is b1, the width of the wire 20 at other locations is b2, and the width of the opening 12 is b3, where b2 ≤ b3 < b1. The width b1 of the wire 20 with the protrusion 50 needs to be greater than the width b2 of the opening 12 of the first accommodating space 11, so that the wire 20 can be fixed by engaging with the sidewall at the opening 12 of the first accommodating space 11 through the protrusion 50. The width b2 of the wire 20 without the protrusion 50 can be understood as the protrusion 50 being the raised portion of the plane containing the sidewall of the wire 20; therefore, the width b1 of the wire 20 with the protrusion 50 needs to be greater than the width b2 of the wire 20 without the protrusion 50. The width b2 of the wire 20 without the protrusion 50 can be less than or equal to the width b3 of the opening 12 of the first accommodating space 11. No specific limitation is made here.

[0055] In some embodiments, a pressing part (not shown) may be provided on the housing 10, and a telescopic part (not shown) may be provided at the opening 12 of the housing 10. The telescopic part is extended and retracted by the pressing part, and the wire 20 is locked and fixed by the telescopic part. Specifically, a pressing part that can control the extension and retraction of the telescopic part is provided on the housing 10. When it is necessary to store the wire 20, the pressing part can be pressed to retract the telescopic part, so that the wire 20 can be stored in the first receiving space 11 through the opening 12. After the wire 20 is stored in the first receiving space 11, the pressing part can be pressed again to extend the telescopic part, so that the wire 20 abuts against one end face of the telescopic part to lock and fix the wire 20. It is understood that when the telescopic part is in the extended state, the width of the opening 12 where the telescopic part is located is smaller than the width of the wire 20.

[0056] In this embodiment, the end of the telescopic part can be flush with the plane of one side end face of the housing 10, thereby avoiding accidental pressing of the pressing part, which would cause the telescopic part to retract and the wire 20 to pop out. The telescopic part can also be provided in two sets: one set is located at the opening 12 of the first portion 111 of the first accommodating space 11, and the other set is located at the opening 12 of the second portion 112 of the first accommodating space 11. The specific arrangement is not specifically limited here.

[0057] In some embodiments, the connection point between the wire 20 and the charging / discharging assembly 30 is located at the end of the first portion 111 away from the second portion 112, that is, the connection point between the wire 20 and the housing 10 is located at one end of the length or width direction of the housing 10. By setting the connection point between the wire 20 and the charging / discharging assembly 30 at the end of the first portion 111 away from the second portion 112, the aforementioned structure that locks the wire 20 in place avoids affecting the stretching of the wire 20 when it needs to be used.

[0058] In other embodiments, the connection position between the wire 20 and the charging / discharging component 30 may be located at one end of the first portion 111 of the first accommodating space 11 near the second portion 112. The specific location can be set according to the requirements, and this application does not make specific limitations here.
